MSL6060L@ compression mode

[Rupert_1]

Hi,
Is there a way to set compression enable on permanantly ?I have a MSL6060L2 tape drive compression frequently defaulted to no , so when backup it uses 3 tapes instead of 2 LTO2 tape media.
Or is it a tape drive problem ?

Rupert,
not a 100% sure, but I think the setting gets lost on unload after completion of backup?!

Rupert,
also, have your tapes been used before to hold compressed data!

Generaly compression is managed by the Backup application, it will issue a scsi code to set Hardware compression on. Some SW some time set Hardware compression off when they finish the backup.
So I would recommand to chek in your backup application if the "set Hardware compression" is enabled for all the backups batch.
Also be sure to not activate Software compression in the same time.
