Frequency of cleaning with cleaning tapes
With modern drives, cleaning is done only when drives say they need…
This is done via “Tape Alert” feature. You configure NetBackup so that the cleaning frequency is set to 0, and it will clean drives only when they request to be cleaned.

Keep in mind that, cleaning a drive too often can cause more harm than good. You should find a good frequency that works for you.

If you face an error like “daemon failed accepting connection 59”

This error can be caused by different things. But first of all, check that there are enough “cleanings remaining” on the cleaning tape used.

Cleaning Tapes from command line

Show the drive name to be cleaned

tpclean -L

Manually clean the drive:

tpclean -C <drive_name>
