we use an LTO drive with an Overland/Tandberg library and Amanda since 2010.
Actual we run a single LTO-7 6tb drive in an Overland NEO T24 and 50 tapes.


sa0 at mpr1 bus 0 scbus5 target 0 lun 0

ch0: <BDT FlexStor II 5.11> Removable Changer SPC-3 SCSI device
ch0: 600.000MB/s transfers

A nice feature with Amanda is that the backup solution
calculates when to make full or incremental backups
of 800+ ZFS datasets.

We allow Amanda to use 2 tapes per backup run (=12tb). Tapes
are picked and changed by Amanda. We have to make sure
that the tapes with the needed label are in the library.

No problems whatsoever.
