AVVI Restore of Differential Backup Restores ONLY Differential Data
- 10 years ago
The problem I saw with HF 212812 (https://support.symantec.com/en_US/article.TECH212812.html) is that
1. Restore of VM from the Differential backup restores only the Differential data, but restore still reports "successful".
2. After this has been tried once, a second attempt still reports successful but even LESS data is restored - apparently only one "shell" vmdk for me.
3. WORST OF ALL, running a restore of the Diff seems to "poison" the WF: once you have tried to restore from the Differential, its parent Weekly Full backup also becomes unusable for full VM restore, restoring "shell" data as in (2) above.
Normal file/folder restores from the Diffs still work.
The "Resolved issue" that I installed HF 212812 for was: "Backup Exec 2010 R3: AVVI restore from an incremental backup set of a virtual machine fails with error - Failed to mount one or more virtual disk images (TECH201706)". The failure was better.
My testing is done. I believe this hotfix is defective, and we will not deploy it.
