correct me if I am wrong:
- If doing backup to tape jobs from a repository
- Veeam checks on per Job basis, if it has full backup files, that are not present on tape. It will copy over all VBK Files it finds, and the last synthesized full.
- Veeam checks on per Job basis, if all incremental are on tape, all missing ones are copied to tapes. (In case you have 3 weeks inc on disk, but only 1 week inc on tape, it would then copy over the old .vib files aswell.
Which is basically fine, you should keep in mind, that backup retention on tape is always higher than on disk.
But is it possible, to have a backup job where it only copies the last synthesized on tape?
On Tape we have:
1st Job: Does full and inc. Full are kept 8 weeks, done weekly sunday with synthesized full. Inc are done daily and kept 3 weeks.
2nd Job: Does monthly full on first thursday of month with synthesized full, also first thursday of the month. No inc.
So that we have retention:
3 weeks daily
8 weeks weekly
12 months monthly
So we noticed, the first time the 2nd Job ran, it copied over all VBK we have in the Media Pool, aswell as the last synthesized full. Thus using quite more tapes as necessary.
What if we only want the last full to be on tape? As we can't set this setting within one Job, we had to do 2 jobs.
Sure, it's just the first backup, that's so big, I assume, any additional backup will do one synthesized per month (even the 1st job does synthesized per week).
But still wondering if I am correct and this would be the correct way to do it.
And if there is a possibility to just have last synthesized Backup on Tape if I want for whatever reason.
