[bareos-users] LTO capacity management

2023-12-20 Thread Alexander Horner
Good evening, I am looking at Bareos as it seems to be the only option that explicitly mentions the use of LTO for incremental backups, so I can keep appending to existing tapes with each backup. Is this indeed how Bareos will work? I am using LTO-5 tapes which have some age and use to them, an

As far as I remember unless you explicitly specify volume size (which can be useful if you're using file-based volumes, bareos will write to the volume until it reaches the end. Then it will request another volume. Unless you hit an error - then I think the volume status will be set to error.

Hi there, thanks for the response, In the case that a volume fails whilst adding it, is it possible to retry a backup with a new volume? On Wednesday, December 20, 2023 at 9:24:38 PM UTC Spadajspadaj wrote: > As far as I remember unless you explicitly specify volume size (which can > be useful

If the writing fails the backup job will end with either failed status or "with errors". I'm not sure but I'd expect the former. You can of course always re-run any job manually but I don't recall any mechanics like "if the job failed, re-try it immediately with another volume". You could try to sc

You certainly will get more gain to spend a bit of time in the documentation, than trying to play with scripting :-) Bareos has parameter to most (if not all) possible case https://docs.bareos.org/bareos-23/Configuration/Director.html#config-Dir_Job_RescheduleOnError ;-) Alexander, if a tap

Thanks MK, Bruno, "Checkpoints also happen on volume changes. This means that when a volume is full, or the backup has to switch to writing to another volume for some other reason, a checkpoint is triggered saving what has been written to that volume." This sounds like what I want to achieve,

As said previously, if the volume is defective, the job try to use another one. But in some cases the drive can be defective, become unresponsive or whatever and the job finish with a job status error. btw Bareos knows where it was on tape ;-) Le jeudi 21 décembre 2023 à 13:56:12 UTC+1, Alexand
