BA923: Volume Shadow Copy Error 0x8004231d - volume in use¶
| Error code | Product | Applies to |
|---|---|---|
| BA923 | BackupAssist ER | BackupAssist ER v1 and later |
Description¶
BackupAssist ER uses Microsoft VSS writers and the VSS service. This error can occur when other applications such as anti-virus software or other backup tools/jobs access the VSS writers or disk space that BackupAssist ER is trying to access.
Resolution¶
Look for applications (besides BackupAssist ER) that could be attempting to access the same volume that the backup process is attempting to back up.
Possibilities include:
- Anti-virus software
- Windows UAC
- Other backup software
- Two backup jobs set to backup the same drive at the same time in BackupAssist ER. (BackupAssist ER only supports 1 backup job running at a time)
Once you're able to stop the conflicting process that is accessing the volume, re-run the backup job.
