BA8207: One or more files/directories failed verification¶
| Error code | Product | Applies to |
|---|---|---|
| BA8207 | BackupAssist | For BackupAssist Classic v12 and later. |
Description¶
During a test restore, BackupAssist verifies the backed-up files against the backup. BA8207 means one or more specific files or directories failed that verification. The details section of the report lists exactly which items failed and the reason for each.
Common causes:
- A genuine read problem - access-permission or disk I/O errors on the backup destination.
- Files whose names contain Unicode or multi-byte characters that were silently excluded by the File Archiving (Zip) engine; these are reported as "File not found in the backup" at verification.
- Intermittent false positives on System Protection test restores, where the listed files are in fact restorable and a re-run succeeds.
Note: on an encrypted backup destination, if the failure was caused by the destination disk being resized or otherwise altered while the test restore was running, BackupAssist reports BA8210 instead of BA8207. On a non-encrypted destination that same external change is not detected separately and may instead be reported here as BA8207.
Resolution¶
Review the files listed in the details section and check whether they can be restored manually. Re-run the verification to confirm whether it was an intermittent failure, and run chkdsk to check for disk errors on the destination. If specific files consistently fail - especially files with non-English names in a File Archiving job - generate diagnostics and contact support.
