Tape replication is completely broken
Whichever operation I try with tape replication it gets broken.
Firstly I could not do a tape rescan of multiple tapes containing concatenated backups as the rescan would not continue on the next tape.
Then I decided to make a replication to only 1 tape, but any repeated attempt on multiple tape rescan would result in the error of the single tape replication operation as half added archives to the index (during a failed replication) would screw up replication to this single tape also.
Then after deleting all the backups from the index and trying a single tape rescan would work but then on subsequent replication to the tape I would get:
Internal error: The backup with GUID 'E8AC4BE6-5280-4E78-8B3C-4148B009396F' already exists in the current backup chain and has ID '1322BE76-96BE-46AB-ACFF-180B8246C788'
What does this mean? I rescanned the tape and it won't add new backup as the old backup has the same name. I don't understand.
You better pray than nothing goes wrong with local index as any attempt at rescan would either fail immediately or it will fail on the next backup.
The only solution is to start with empty tape and hope you never have to rescan it again. This isn't how reality works.
There is always unpredictable situation where you need to rescan the tape. Acronis please fix this!!!
