I've contacted Veeam support some months ago because of this, but their answers were not very helpful. I think they simply didn't understand what i have to achieve.
We're doing several weekly full backups (Active or Synthetic) every Friday to Saturday night using multiple jobs. The rest of the week daily incrementals are created. Every day, the backups have to copied to tape. But for the incrementals, i have to have all incrementals of the week on one tape, every day. The reason to do it this was is, that i don't want to read seven tapes in the worst case to get all required backup files for a restore, but only two (The full backup and the newest tape with all the incrementals)
So, at the end of the week, i should end up with the following tapes:
Tape 1 (Full): Full Backups (from Friday)
Tape 2 (Inc): Incrementals (from Saturday)
Tape 3 (Inc): Incrementals (from Sat, Sun)
Tape 4 (Inc): Incrementals (from Sat, Sun, Mon)
Tape 5 (Inc): Incrementals (from Sat, Sun, Mon, Tue)
Tape 6 (Inc): Incrementals (from Sat, Sun, Mon, Tue, Wed)
Tape 7 (Inc): Incrementals (from Sat, Sun, Mon, Tue, Wed, Thu)
Don't think this is possible using the GUI only. Maybe someone knows if that can be done using PowerShell somehow?
Long time ago, before Veeam supported tape drives, i wrote a PowerShell script for BackupExec doing exactly this. Works perfectly fine, but really would like to get rid of the BE crap if possible.
