Incremental backup with Archive bit set completes with status 0, but some files don't backup and Archive bit is cleared
Severity
Possible Data Loss
Description
Incremental backup with Archive bit set completes with status 0, but some files are not included in the backup even though the Archive bit on those files are cleared.
This issue occurs when files are moved into the folder being backed up immediately after the backup is started. If the files are moved into the folder just after the backup is started, they will not yet exist when bpbkar creates the snapshot. During cleanup task, the archive bits are cleared for those files whose modify and create time is less than the backup start time.
Action Required
An Emergency Engineering Binary can be obtained by contacting NetBackup Technical Support and referencing the EEB for Etrack 3973889.
Install on: Client
The issue may also be resolved by implementing the following workaround.
- Enable Multi Stream option in the backup policy.
- Take Incremental backups based on Time Stamp.
- Enable TIR with Move detection in the backup policy.
