Parallel recording on two tapes

[Ramil]

Can I set up parallel recording on two tapes in one job? That is, not in two different jobs. It is in one job, because run "before" and "after" scripts.

No, this is not possible.

Sorry for not expressing my point fully. I still don't know how to convey the meaning correctly...

The data obtained during the execution of one job must be written to two tapes in parallel.

In this configuration, data is written to a single tape. But it is necessary that the data be simultaneously duplicated on the second tape.

It is possible to run a second job to write to a second tape, but in this case the "RunBeforeJob" script is executed, and only after it has been executed will the backup data appear.

Isn't that what Copy job is for?

Sure, you have that short period after the original job had been run and the Copy job wasn't run yet but it's usually relatively acceptable.

In order for the second task to duplicate the data on the second tape, you need to know when the script will be executed and the data for backup will be ready.

Hi Ramil,

That's not supported by Bareos. If you really need to have two tapes
written at once, you'll either need some kind of appliance that does
that (i.e. maybe some tape vendor offers something like that) or you can
try to fund development of that feature in Bareos.

Best Regards,
Andreas
