Full account backups can fail due to insufficient free space, oversized accounts, transient load, or storage destination issues.
Common symptoms
- The backup never appears
- The process fails silently
- Partial archives are created but unusable
Troubleshooting steps
- Check available disk space in the account before generating a backup.
- Avoid running large backup operations during peak application activity if the site is resource-sensitive.
- If remote backup destinations are supported, confirm the destination is reachable and correctly configured.
- Delete old temporary backup archives that may consume quota.
- After generation, verify the archive size is reasonable and the file downloads successfully before relying on it.
Additional notes
- A full backup needs working space during creation, not just final archive space.
- Very large mail stores can make backup creation appear stalled.
When to contact support
Contact support if backup generation consistently fails despite sufficient free space.
