Fibercool -
It sounds like your VDP performed a rollback during the reboot.
When this occurs, it will roll back to the last validated checkpoint. Question would be when was that checkpoint created.
Things to check would be - in the /usr/local/avamar/var/log/ab_boot.rb.log, you would see an entry that said 'performing rollback to ...' and it would list a checkpoint name. The name of the checkpoint is formatted with the date in it. That would let you know what date it rolled back to.
