General
1.1.
Can you briefly explain the idea of how Backup2Go Professional Online
Backup Services work?
The
Backup2Go Professional Online Backup Services consists of 3 main
modules:
1.
The client software – Backup2Go Professional Online Backup
Software (B2GoPro)
2.
The server software – Backup2Go Online Backup Server (OBS)
3.
The replication server – Backup2Go Online Replication Server
(ORS)
B2GoPro
is
a client application with a user-interface for easy backup
configuration. It allows users to upload selected files to the Online
Backup server and runs scheduled backup jobs. It also allows users to
create different backup sets for different backup purpose. Besides
file backup, B2GoPro can backup a list of applications such as MS
Exchange, MS SQL, Oracle, MySQL, Lotus Domino, and much more. B2GoPRO
supports Windows 2000, XP, 2003, Linux, Mac OS X, etc.
OBS
is
a server application which store backup data from multiple B2GoPRO
backup accounts. It has a web-based Management Console for Users so
they can logon to manage their own backup account or restore their
own backup data.
ORS
is
another server application running on a separate server to that of
the OBS, it provides close to real-time backup for multiple OBSs. So
even if one of the OBS failed, the RPS still has a copy of the backup
data.
The
relationships of the Online Backup Suite are depicted in the diagram
below.

The Windows version of B2GoPRO installer hangs, what could be the
problem?
There
are few things that could create errors during or after executing the
installer.
1.
Make sure there is enough disk space on the machine.
2.
Make sure you do not have any anti virus software or PCanywhere
running, as this may create problems with InstallAnywhere installers.
3.
There are also problems with InstallAnywhere installers and Dell
OpenManager. If OpenManager has installed on the target system, be
sure to disable it before installing B2GoPRO.
4.
Hardware could cause errors as well, try set your [hardware
acceleration display setting] to off. There are problems with certain
versions of Java running along with certain video cards.
5.
This may only be a Java problem.
Also,
if you are transferring this file from one machine to another, please
be sure the file size is valid and you are transferring the file in
binary mode.
Java
Testing
Please
try running any of the Swing demos that came with the Java runtime in
1.4.X and see if it hangs on Windows. In order to fix this problem,
some knowledge base on the Internet suggested updating DirectX to at
least DirectX 8.1. Most machines got this problem had DirectX 7.0
installed. (You can use the “dxdiag” command to find out
the directX version)
SUN
recommended two workarounds for certain video card issues
1.
The following will pass properties to the installer's Virtual
Machine: In Advanced Designer – Project -> Config ->
Additional Arguments set that to "-Dsun.java2d.d3d=false
-Dsun.java2d.noddraw=true" without the quotes.
2.
Set the following lax property in your LaunchAnywhere for your
application's JVM:
lax.nl.java.option.additional=-Dsun.java2d.d3d=false
-Dsun.java2d.noddraw=true Add the same line to the uninstaller lax
file, using a modify file action in your installer in post-install.

2.10.
How does B2GoPRO detect changes in files? Does it use the Archive
bit? Some tape backup software resets the Archive bit. Would this
affect B2GoPRO when backing up the same data?
B2GoPRO
compares timestamps of files on the server with the corresponding
copies on client machine. Archive bit is not used as it does not
detect relocated files. Therefore tape backup would not affect
B2GoPRO.
Back To Top
2.11.
Does B2GoPRO copy the same set of files regularly?
After
the initial upload, subsequent backup jobs will only transfer the
modified or new data to the Backup server. It depends on the nature
of the data, but normally, less than 2% of all data is modified.
2.12.
Transfer Block Size is 128Kb by default. Is there a reason for this?
Backup
data is transferred in blocks (instead of file by file) to minimize
connection negotiation roundtrips. It is not the TCP/IP block size.
This setting is optimal for the backup operation.
Back To Top
2.13.
How can I backup a huge data set over the Internet?
If
you have a lot of data (e.g. 300GB) to backup to the backup server,
it would take a considerable amount of time to perform the first full
backup over the Internet. You can try the following method:
1.
Use the Seed
Loading Utility to
backup your backup set to a local hard disk (instead of directly
transfer to the backup server)
2.
Send the backup data, using a removable hard disk, to your backup
service provider.
3.
The administrator can then load all your backup files from your
removable hard disk into your backup account. This could save you
days (even weeks) of performing your first full backup.
In
addition, subsequent backups are incremental (only new or updated
files will be uploaded to the server), the amount of data transfer
should be relatively small.
Please
refer to the User’s Guide for details on the “Seed
Loading Utility”.
Back To Top
2.14.
What is the best way to restore a huge data set?
The
Backup2Go support team can copy the data of the particular backup set
from our Online Backup Servers to a removable media, e.g. external
hard disk, and ship it directly to you. You can then use the “Decypt
Files Tool”
in B2GoPRO to restore the backup data from the removable media to its
original format. (Note: Charges may occur for large restores. Contact
support@backup2go.com.au for pricing)
Back To Top
2.15.
Does In-File Delta backup require a temporary working directory?
B2GoPRO
requires a temporary storage for the delta file before it gets sent
to the server.
For
example:
If
you have a 10GB file that has already been backed up to the server
and you have updated 10MB of this file. Then you need to have at
least 10MB of free space in the temporary directory for the delta
file.
*Note:
Certainly you do not need 10GB of free disk space.
Also,
if you want to backup 5 x 10GB files in the same situation. You will
only need 10MB of free space (not 5 x 10MB), because each delta file
will be automatically deleted right after it has been backed up.
Back To Top
2.16.
What is the average compression ratio?
All
backup files are compressed and encrypted before uploading to the
Online
Backup Server,
the average compression ratio for text-based file is around 4:1.
However, no further compression can be made on files that are already
in compressed format (e.g. JPG, ZIP). In general, you can assume a
2:1 compression ratio when you are backing up a file set with variety
types.
Back To Top
2.17.
Can I change my encrypting key?
The
encrypting key cannot be changed once you setup your Backup Set. This
is necessary for the integrity of the Backup Set, making sure that
backup data is only encrypted by one key. Otherwise, you will have
problems remember two encrypting keys when you want to restore your
files in the future.
You
need to recreate your Backup Set if you really want to change your
encrypting key.
Back To Top
2.18.
If the “Use Login Password as Encrypting Key” option was
selected when creating the backup set. Why I cannot restore the
backup data with my most current login password?
By
selecting the “User Login Password as Encrypting Key”
option when creating a backup set, B2GoPRO will set your login
password as the encrypting key for the backup set. Once set, even if
you change your login password afterward, the encrypting key will
remain as your original password. In other words, if you have changed
your login password, you still need to use the original password to
decrypt and restore the backup set.
Currently,
if the encrypting key is forgotten or lost, the backup set can never
be restored. It is not possible to restore without the key.
Back To Top
2.19.
What kind of encryption used by B2GoPRO?
There
are two encryptions being performed by B2GoPRO:
1.
Encryption
of backup data -
This is being done by 128-bit symmetric key encryption (AES,
TripleDES, TwoFish). 256-bit is not available because it requires too
much CPU and it is not really required. (128-bit is currently being
used by most banks)
2.
Encryption
of backup traffic -
This is being done by 1024 bit RSA public key encryption. The
strength of the encryption depends on the key size you use when you
generate your CSR before submitting to your CA. 1024 bit is what is
being used by most CAs.

2.20.
When select the backup option “local hard drive” to
backup to external hard drive, it fails in the middle of the process,
why?
Please
check if the external hard drive is in FAT32 volume format. And also
check whether there is any folder containing more than 32000 files
and there is no file bigger than 4GB within your backup set. It is a
FAT32 limitation, you may try to convert the FAT32 volume to NTFS.

Scheduled backup jobs are not running on my Windows machine, why?
Please
try the followings:
1.
Check if [Control Panel] -> [Administrative Tools] ->
[Services] -> [Online Backup Scheduler] is available and started
2.
Check if C:\Program Files\B2GoPRO\home.txt contains the home
directory for your backup account (e.g. C:\Documents and
Settings\Administrator\.obm)
3.
Check if C:\Program Files\B2GoPRO\jvm\bin\SchedulerB2GoPRO.exe exists
4.
Check if C:\Program Files\B2GoPRO\log\Scheduler\info.log contains the
startup loading entry, e.g.
i.

I am having problems with my scheduled backup, why?
If
you are backing up files from a network drive, please check if you
have included the valid “Network Resources Authentication”
information for the backup set. This is required for scheduled
backups that access any network resources.
You

I cannot get proxy authentication to work with B2GoPRO, why?
If
you are using port 80, please check whether your proxy server accepts
"HTTP CONNECT" calls on port 80. You may also want to try
other ports like 443 to see if your proxy server accepts that.

Can I backup an entire Operating System?
Currently,
it is not possible to do hard disk image backup with B2GoPRO.
However, you can still backup/restore the operating system by doing
the followings:
To
backup all files including the operating system, please do this:
1.
Add all files to your backup source
2.
Add a SystemState backup type to your backup account (Windows only)
To
restore all files including the operating system, please do this:
1.
Re-install the operating system and applications
2.
Restore the SystemState backup to your machine (Windows only) - To
restore the System State data on a domain controller, you must first
start your computer in a special startup option called "Directory
Services Restore Mode". To access "Directory Services
Restore Mode", press F8 during startup and select it from the
list of startup options.

Windows network map drive connections are not stable, why?
You
may want to try editing a few Windows Parameters.
SMB
Size
When
running applications that copy or move a large amount of data to a
remote server, the speed of such action is determined by network
speed and by the SMB (a protocal related to Windows map drive) size.
NT/2000
negotiates the SMB size and will generally set this to 4K blocks for
applications that are moving or copying data to a remote server. By
increasing this block size, you will allow the server to complete its
file copies faster. This will increase the performance of the
application making the copy/move calls.

What are the advantages and disadvantages of backing up multiple
computers using a single backup account?
Advantages
��
You
require less backup accounts
��
You
can use one username and password to configure the backup setting for
all Backup Sets
Disadvantages
��
You
must use different backup sets for different computers
��
Whenever
a new backup set is created under the backup account, you need to go
back to all computers using the same backup account to uncheck the
“Run
scheduled backup on this computer”
option for the new backup set (Since backup setting is saved on
server and new backup set is default to run on all computers, i.e.
with the option checked).
��
Improper
configuration could easily cause problems, which are difficult to
debug.

Is it possible to do incremental or differential backups with MySQL?
MySQL
backup is done with SQL Dump file, and it generates a single file
which is then uploaded. These backup files usually very large size
and it takes time to backup to the server. At this moment, it is not
possible to do incremental dump with mysqldump. But our In-File Delta
feature shall ensure that, instead of the entire backup file, only
the changed data blocks within the dump file are uploaded to the
Backup Server.

How does the “Remove retention files for overlap policy”
under Advanced Retention Policy work?
In
general, daily snapshots followed by a weekly snapshot or a monthly
snapshot, etc. will be removed; weekly snapshots followed by a
monthly snapshot or a quarterly snapshot, etc. will be removed; and
so on.
This
is illustrated by the following example.
Assume
today is 17Jan06, and the Advanced Retention Policy is as follows:
��
Daily:
retain for 7 days
��
Weekly:
retain for 4 weeks (the job will be performed on Saturday)
��
Monthly:
retain for 3 months (the job will be performed on 1st of each month)
If
“Remove
retention files for overlap policy”
is NOT enabled:
Then
a total of 14 snapshots (7+4+3) will be kept on the server
accordingly, i.e.:
(Daily):
10Jan06, 11Jan06, 12Jan06, 13Jan06, 14Jan06, 15Jan06, 16Jan06
(Weekly):
24Dec05, 31Dec05, 7Jan06, 14Jan06
(Monthly):
1Nov05, 1Dec05, 1Jan06
If
“Remove
retention files for overlap policy”
is enabled:
Then
only the following snapshots are kept: 1Nov05, 1Dec05, 1Jan06,
14Jan06, 15Jan06, 16Jan06.
Specifically,
the weekly policy overrides the daily policy so 10Jan06, 11Jan06,
12Jan06 and 13Jan06 will be removed. The monthly policy overrides the
weekly policy, and 24Dec05, 31Dec05 and 7Jan06 will be removed as
well.

What is incremental backup and how does In-File Delta work?
In
an incremental backup, only modified files will be uploaded to the
Backup Server.
On
the other hand, In-File Delta is applicable to the physical files to
be uploaded to the Backup Server, does not matter whether it is a MS
SQL database file, MS Exchange transaction log file or any normal
file in a FileBackupSet. Specifically, only the changed blocks in
comparison to the original file on the Backup Server (delta file)
will be uploaded.
For
each modified file, B2GoPRO would determine whether the entire file
or only delta file should be uploaded. If the entire file is to be
uploaded, the old version of the file will be moved to the Retention
area. Else if only the delta file is to be uploaded, the previous
delta files will be moved to the Retention area and the Data area
should contain the original full backup file, checksum file and the
latest delta file of this file.

2.35.
How does the “Auto” block size work under In-file Delta
settings?
If
the block size is set to “Auto”,
the effective block size (Started from B2GoPRO v5.0.1.7) will be
chosen from the following table based on the file size of the updated
file:
File
Size Delta Block Size
------------
----------------
0
- 500M 4k

- 2G 8k

What happens when we do In-File Delta backup on a directory?
When
you do backup, the Online Backup software will do the followings:
1.
Check if any files are added, updated or deleted (the calculation of
these files are based on files having the same filename).
2.
New files will be uploaded to the server in whole.
3.
Deleted files will be removed from Data area and placed into the
Retention area on the Backup server.
4.
Updated files will be processed by the In-File delta option (i.e.
only changed data blocks within the files will be uploaded to the
Backup Server)

Does B2GoPRO have to stop the application when doing online backups?
B2GoPRO
can backup application data while the application is still running.
Particularly, we have special agents for MS Exchange Server, MS SQL
Server, Oracle, Lotus Notes and MySQL, which allows these
applications to be backed up while they are online. With the Volume
Shadow Copy feature
started from B2GoPRO v5.0, we are able to backup other types of
applications while they are online.

What are Off-line backup, Logout backup reminder and Local backup
features?
Off-line
Backup is
basically designed for notebook users who are off-line most of the
time, and cannot rely on backup schedule to backup regularly. The
backup interval allows notebook users to specify the interval that
they would like their data to backup. If this interval has elapsed,
backup will run automatically once this machine is online.
Logout
Backup Reminder asks
user if they would like to backup if they logout of the computer or
shutdown their computer.
Local
Backup allows
an extra copy of backup file to be kept on local hard disk when
backup is running.

The MS SQL or MS Exchange database backup job stores 2 copies of the
spooled database file in the "temporary directory" (tagged
with different datetimes). This has taken up extra disk space, is
this necessary?
If
you have interrupted any of the backup jobs, the file tagged with the
datetime of the corresponding backup job will be renamed to its
original filename just before it is uploaded. This is necessary as we
need to ensure that the snapshot of different dates would not
overwrite each other.
If
a backup job is still running, just let it runs to completion. If
backup has been stopped already, just remove all files tagged with
the corresponding datetime in the “temporary directory”

What do I have to do in order to backup open files?
You
need to be on B2GoPRO v5.0 or above, as well as support from the
underlying OS. Windows XP and 2003, by default, come with Volume
Shadow Copy,
which allows backup open file. For older platforms, e.g. Windows
9x/ME/NT/2000 or NetWare, we would recommend adding a third party
open file manager option (e.g. St. Bernard Open File Manager -
http://www.stbernard.com/)
which might cost around US$100 for each workstation and US$300 for
each server if open file backup is required.
*Open
file option is not required on Linux/Unix/Mac OS X because no files
are held exclusively open by applications.

"The process cannot access the file because another process has
locked a portion of the file"
You
get this message when backing up “C:\xxx\yyy\zzz.txt”
because another application has held a read-exclusive lock on
“C:\xxx\yyy\zzz.txt”. The backup agent, therefore, is
unable to open the file to read its content. Please try the
followings to resolve this problem:
��
Enable
the Volume Shadow Copy option for the corresponding backup set if you
are on Windows 2003 or XP.
��
If
you are on an older version for Windows, you may need to obtain a
generic “Open File Manager” in order to backup the locked
files.
��
If
the locked file is not important (e.g. C:\pagefile.sys), simply
exclude the locked file from your backup source. By doing so, this
message will not appear again.
��
If
the locked file is a database file held open by one of our supported
applications (e.g. Microsoft SQL Server, Microsoft Exchange Server,
Oracle, Lotus Domino/Notes, MySQL), simply use the corresponding
add-on module provided to backup the database. This way, you can
backup the database you want (using the application specific APIs)
without accessing the database file directly.
��
If
the locked file is a file held open by some other third party
applications, you can use the [Pre/Post Command Line Tool] to
shutdown/restart the application that is locking the file
before/after a backup job to make sure that no locks will be placed
on files that you need to backup.

" [Microsoft][ODBC SQL Server Driver][SQL Server]The statement
BACKUP LOG is not allowed while the recovery model is SIMPLE"
You
need to change the Recovery model to FULL. If you are using Microsoft
SQL Server 7.0/2000, please refer to the following screenshots:
1.

2.

If
you are using MSDE, please issue the following commands:
osql
-E -S [Server Name] -Q "ALTER DATABASE [Database Name] SET
RECOVERY FULL"
These
will enable transaction logging option for your MSDE databases and
allow incremental/differential backup to be run with no problems.

"CExBackup::backupService:HrESEBackupSetup: Error Number
0xc800020e: An incremental backup cannot be performed when circular
logging is enabled"
You
need to disable circular logging in MS Exchange. Please uncheck the
[Enable circular logging] option as shown below and restart the
“Microsoft Exchange Information Store” service after you
are done.

"CExBackup::backupStorageGroup:HrESEBackupTruncateLogs: Error
Number 0xc7ff1004: (null) "
This
is an error returned by the Microsoft API and is a Microsoft issue.
Please try to restart the "Microsoft Exchange Information Store”
service. If the problem persists, you may want to schedule the
service to restart on a daily basis.

"CExBackup::backupStorageGroupLog:HrESEBackupGetLogAndPatchFiles:
Error Number 0xc8000232: Some log or patch files are missing"
If
you have just disabled the MS Exchange circular logging option,
please try running a full backup again, this should fix the problem.

"CExBackup::backupFile:WriteFile: Error Number 0x6: The handle
is invalid"
This
is the MS Exchange having problem in writing to the Temporary
spooling directory. Please ensure that the system account running the
MS Exchange has full access right to that directory. If it is a
network drive, please use an UNC path (e.g. \\server\share), and the
“Network Resources Authentication for Windows” is
properly set for the corresponding backup set.

"Path ‘C:\Temp\MSSQLServer\1137040769567’ does not
exist"
If
you get this error while you are doing MS SQL or MS Exchange backup,
please try to use an UNC path (e.g. //server/share) in "Temporary
directory for storing backup files" under [Backup Source
Settings]. Please make sure that your B2GoPRO is on the same machine
as your MS SQL or MS Exchange. Please also ensure that you have
included the appropriate “Network
Resources Authentication for Windows”
information in the backup set.
For
MS SQL Server, you may want to check whether if it can spool the
database file correctly by running the following command:
(Windows
Authentication mode)
osql
-E -Q "DECLARE @dbname char(64) SET @dbname = 'xxx' BACKUP
DATABASE @dbname TO DISK = '//server/share/abc.txt' WITH SKIP"
OR
(SQL
Server Authentication mode)
osql
-U USERNAME -P PASSWORD -Q "DECLARE @dbname char(64) SET @dbname
= 'xxx' BACKUP DATABASE @dbname TO DISK = '//server/share/abc.txt'
WITH SKIP"
Note:
USERNAME/PASSWORD
= the database username/password xxx = the database that you would
like to backup //server/share/abc.txt = the location for the database
spooling file

"Expect log sequence 'xxx' but found 'SERVERNAME\Microsoft
Information Store\First Storage Group\E000xxx.log'"
This
occurs when the log sequence of MS Exchange was altered by other
backup software, e.g. NTBackup. Thus when the Backup Manager next
performs a MS Exchange backup, the Exchange log sequence would not
match the one that it is expecting. With the broken sequence, the
Exchange server cannot be restored to its latest state.
To
resolve this problem, you need to deactivate all other backup
software that is operating on MS Exchange, and then you need to
perform a Full MS Exchange database backup manually via the Backup
Manager.
Alternatively,
instead of backing up transaction logs during the weekdays, you can
consider doing Full Exchange Database backup on a daily basis with
the In-File Delta option enabled. This should avoid interference from
other backup software while keeping the amount of upload data to
minimal.

"The last backup jobs of *.stm (2006-10-30-13-40-21) and *.edb
(2006-11-04-03-05-00) don’t match for database
'ServerX\Microsoft Information Store\First Storage Group\Mailbox
Store (ServerX)'"
For
MS Exchange backup, *.stm and *.edb are backed up in pairs, if this
error occurs, it implies that during a previous backup, there was a
problem with either the *.stm or *.edb file. If this happens, please
perform a Full MS Exchange backup manually via the Backup Manger to
resolve this problem.

"No *.stm found for database 'ServerX\Microsoft Information
Store\First Storage Group\Mailbox Store (ServerX)'"
This
suggests that the .stm file on server may have been corrupted or
found missing. To resolve this error, please perform a Full MS
Exchange backup manually via B2GoPRO.

Exception in thread "main" java.lang.UnsatisfiedLinkError:
/usr/local/B2GoPRO/jvm/lib/i386/libawt.so: libXp.so.6: cannot open
shared object file: No such file or directory…
This
is caused by a missing library in Fedora Core 6. To
resolve this, just open a terminal window. From here type in the
command 'yum install libXp' (please note that the command is case
sensitive), this will ask you if it is ok to download the package.
Just type 'Y' and the libXp library will be installed. Once
installed, just run the command "sh
$B2GoPRO_HOME/bin/RunBackupManager.sh" You should find that the
B2GoPRO will open up and you should be able to create the backup set
via the GUI interface. When running the 'yun install' command, you
may see the following error: Loading "installonlyn" plugin
Existing lock /var/run/yum.pid: another copy is running. Aborting.
This is because the background YUM updater service is running. To
stop it, run: /etc/init.d/yum-updatesd stop Once the process has been
stop, you should be able to run the command 'yum install libXp'
without any problems.
