i want to use tape backup without a changer. For a small installation ( complete backup fits on one tape ) i want to create something with minimal user interaction.
X tapes are available and in the worst case, the user should be able to insert a random tape and take one offline.
The only thing he must take care of, is that a new tape is inserted and no tape stays ejected.
Only with the gui something like this seems not to be possible, as a job starts a single pool with attached named tapes and then expects the right names at execution.
Did i overlook something?
I helped myself with an unelegant script:
( edited version from 05.05.24 without using jobs, better error capturing )
This seems to work, but is there a simpler way to achieve my goal?
Greetings
