Could not read destination file

Error code	Product	Applies to
BA733	BackupAssist	BackupAssist v5 and later

Description

This error occurs when one or more files on the backup destination cannot be read by BackupAssist.

Resolution

There are 4 possible resolutions for this problem

Resolution 1 - Check the Backup User Identity's permissions

Check that your Backup User Identity has been set and has the required access. To view your current Backup User Identity, select the Settings tab > Backup User Identity and you'll see the following dialogue box appear.

Note: For BackupAssist 10.4.2 and earlier, the Backup User Identity is used for all backup jobs and the account may have been created with custom access levels. For 10.4.3 and later, a Backup User Identity is only required for Jobs that have a NAS destination or the SQL add-on, and in these cases, the Backup User Identity should be a member of the Administrators group.

What to check

• For BackupAssist 10.4.2 or earlier - check that the account is still selected, enabled and has the required access.
• For BackupAssist 10.4.3 and later, check that the account is still selected, enabled and a member of the administrators group.
• To check the permissions properly, you can log into the backup server using the Backup User Identity account and check that you can read and write to the backup destination without any authentication requests or errors.
• If backup account's password is changed in Windows, it will need to be changed in BackupAssist.

Resolution 2 - Check for any process conflicts

Processes that are running at the same time as BackupAssist can interfere and could cause this error.

Check that you are not running the following processes at the same time as your backup job:

• Anti-virus scans (including live scanning features)

It is recommended that all anti-virus processes are disabled while the backup job is running to avoid any conflicts. If you are not sure how to configure this, you may need to contact your anti-virus vendor for assistance.

Try placing an exception for BackupAssist within or disable your anti-virus software and run the backup again to see if the error is generated again. If it is, then it means that your anti-virus is marking BackupAssist as a threat to your system. To re-configure your anti-virus avoid such a conflict, we recommend that you contact your anti-virus support vendor for further advice.

• Defragmentation processes

More information on this process is located at http://windows.microsoft.com/en-au/windows/improve-performance-defragmenting-hard-disk#1TC=windows-7.

• Consistency checks such as chkdsk scans

Please review the following document from Microsoft on the use of chkdsk: https://technet.microsoft.com/en-us/magazine/ee872425.aspx

If any of the problems described in the article are occurring, reschedule one of the processes to a later time to avoid the conflict.

Resolution 3 - Check if any files are open

If the files are on a network drive
BackupAssist does not support open files on a network share. You will need to make sure the files are not in use during the backup, or install BackupAssist on the network share.

If the files are on a local drive
Make sure that the Microsoft Volume Shadow Copy Service is enabled within the backup job.

The steps to do this are as follows:

1. Open BackupAssist.
2. Select Manage Backup Jobs.
3. Select the backup job.
4. Select Edit from the top menu.
5. Select Open Files from the options on the left.
6. Tick Microsoft Volume Shadow Copy Service and save your changes.

Resolution 4 - Check NAS firmware and drivers are up to date

You should also check that the NAS drivers and firmware are up to date. The drivers and firmware will be available from your NAS vendor.
