BA2560: Unable to complete catalogue using MFT parser¶
| Error code | Product | Applies to |
|---|---|---|
| BA2560 | BackupAssist | For BackupAssist 15.0.0 or later. |
Description¶
Unable to complete catalogue creation by using MFT parser.
Resolution¶
BackupAssist builds the file catalogue by reading the volume's Master File Table (MFT) directly, which is fast. This warning means the MFT could not be read reliably, usually because of minor NTFS inconsistencies on the volume.
Resolution 1 - Repair the volume with chkdsk (recommended)¶
From an elevated command prompt, run a check-disk on the affected volume - for the volume with drive letter X, run "chkdsk X: /f". Note that "chkdsk /f" needs exclusive access and dismounts the volume while it runs; on a volume that is in use (such as the system drive) it runs at the next restart, so schedule it outside backup and production hours. Re-run the backup once the volume is clean.
Resolution 2 - Disable MFT parsing (advanced, with guidance from technical support)¶
If the volume cannot be repaired, Support may direct you to have BackupAssist use the slower legacy traverser instead of the MFT parser. This is controlled by a registry value (DisableMFTParsing) under HKLM\SOFTWARE\Cortex I.T\BackupAssist\v{major}; contact Support before changing it. The catalogue is then built more slowly but without relying on the MFT.
