After upgrading the backup server from version 6 to 8.1 or above, the following error message is displayed when performing a backup of any type:
No. | Type | Timestamp | Log |
* | info | YYYY/MM/DD hh:mm:ss | ... |

* | erro | YYYY/MM/DD hh:mm:ss |
Unable to do backup, Error= [MigrateV6Index.downloadV6Index]
Failed to download v6 index |

* | erro | ... | null |
This issue can occurs if the index file of the corresponding backup set is corrupted before the upgrade. The corrupted index file cannot be retrieved for the sub-sequence backup jobs after the upgrade.
To resolve the issue, perform a single backup set rebuild for the corresponding backup set, and then perform another backup job afterward.
