Incremental Backup to Tape or File to tape

[weberm]

Hey guys,

is it possible to safe only incemental backups to tape?

Currently we create a synthetic full on Sunday.
Under the weekdays we create incrementals and want to safe them to tape. Is this possible with Backup to Tape or only with Files to Tape.

Sun: Synth. Full
Mon: Incremental
Tue: Incremental
Wen: Incremental
Thu: Incremental
Fri: Incremental
Sat: Incremental
Sun: Synth. Full

We change daily the incremental tapes and the last full backup in the month get locked away for a year.

Hello Mark and welcome to the community!
What is the purpose of writing only increments on tape?
If you want to have a restorable copies on tapes, you need both fulls and increments.
Thanks

No, as soon as you skip synthetic full backup created on Sunday, the further restore points (created starting from Monday) will become unrestorable. The reason is you won't have on tapes a full backup those restore points depend on. Thanks!

Fist of all: happy new year. Thank you very much for the fast replies. My late answer is late due to the holidays. I just came up with a new concept for or Backup to Disk strategy. I´m quite new to veeam so sorry for the newbie questions. I´ve read the manuel but couldnt find a satisfying answer.

So i came up with the following concept:

Backup to Disk

Sun: Synth. Full
Mon: Incr.
Tue: Incr.
Wen: Incr.
Thu: Incr.
Fri: Incr.
Sat: Incr.
Sun: Synth. Full

Backup to Tape

2 Sets of Tape á 4 Tapes

Sun: Synth. Full
Mon: Sun + Incr. Mon --> Set 1
Tue: Sun + Incr. Mon + Incr. Tue --> Set 2
Wen: Sun + Incr. Mon + Incr. Tue + Incr. Wen --> Set 1
Thu: Sun + Incr. Mon + Incr. Tue + Incr. Wen + Incr. Thu --> Set 2
Fri: Sun + Incr. Mon + Incr. Tue + Incr. Wen + Incr. Thu + Incr. Fri --> Set 1
Sat: Incr.
Sun: Synth. Full

So is there a way to tell the Backup to Tape Job to write the Synthetic Full + incrementals per day from the current week?
Because in the next week i dont want the "old" backups on tape.

Happy New Year to you too Marc!

Sounds like you need at least two tape jobs to keep Set 1 and Set 2 isolated from each other. As for overwriting the tapes - you can define one week retention on the media pool and it should be applied to the tapes in your media pool. Cheers!
