I got a client with a small backup solution (~1.5TB, ~25 VMs, ~8 B2D jobs doing synthetic fulls every night, one SureBackup job, one D2T job, one external LTO-5 standalone drive) where "everything has to fit on a single tape in one night"-scenario. This works well, until the tape (LTO-5, ~1.3 TB) runs full and gets ejected in the middle of the night. The tape job waits for the next tape and eventually runs out of time, backup-to-tape incompleted. There's no mechanical changer. Tapes get switched on the next day by an employee.
So the idea would be to expand tape capacity by adding another external tape drive to the same job. This way everything would fit on the loaded tape(s) without changing.
Question is: does B&R v8 support two or more drives in the same job and splits the data across those drives/tapes? Does this even work if there's a tape server involved?
I've not the liberty to try and test without disrupting the backup system in place right now. So any advice is much appreciated.
