Backup to Tape always FULL

Veeam Logoby jbrullemans » Thu Oct 26, 2017 7:26 am

Hi,

Because of the increase of ransomware around the world the only way to have a complete offline backup is in mine opion still a tape solution. Backup to the cloud can still be compromised if credentails are cracked.
Currently our backup jobs are forward incremental with active full on saturday.
So what i would to achieve is that on working days a the full backup chain (or virtual full) is backupped to the tape streamer. So on monday it is the Full of sa with incrementals of su-mo. on tuesday it is : full of saturday and incrementals of su-mo-tu etc. etc.

Does anyone know how to configure this? i tried virtual full on every day but that doesn't seem to work. I don't want to backup only the incremenals because in case of a disaster this could result in using 6 tapes to restore.

The physical setup for this will be : local server with 12 or more hd spindels with local attached VTL LTO7.

What specific issues you encountered with daily virtual full backup? What backup mode does a source backup job use?

Hi,
The problem with daily virtual full is that is doesn't do a daily full it just writes the incremental to tape.
The source backup mode is forward incremental with active full on saturday.

Try to switch:

1) Either to reversed incremental mode
2) Or to forward forever incremental and daily virtual full backup

This way, the .vbk file will be copied or created on tapes on everyday basis.

Thanks.

Hi Eremin,

That is exactly what i don't want. Revesere incremental is to slow.
but forward forever you mean? don't do active or synthetic full and use virtual full for tape? Aint there another way? forever incremental is a little bit scary i think beause the you never reset the backup chain.

Correct.

Aint there another way?

I doubt that you will manage to copy full backup daily with any other approach.

forever incremental is a little bit scary i think beause the you never reset the backup chain.

With periodic SureBackup and health checks, you should be OK.

Thanks.

Hi John. If a source job is forward incremental with periodic fulls enabled the tape job won't write synthetic fulls. That's by design (see note).

As a trick you may try to use in the tape job a pre-job powershell script which disables synthetic fulls in the source job and a post-job script which enables them again.

Where or how can I submit a feature request ?

As described above, backup to tape (offline storage) is the only way to be 100% sure that hackers won't be able to destroy or encrypt all your data.

I too need a full backup to tape every single day, but still want to use incremental backup for the preceeding backup-to-disk job.

Yes I know reverse incremental exists, but it is slow, and available only for VM's. I also use Veeam agent for a number of physical servers, and reverse incremental is not available for agent based backups.

I mean how stupid is it, that if you do periodic active or synthetic full to disk, as a result you cannot do virtual full to tape. ????

You've already done it by posting here.

It's not, if you think about the idea or the use case behind tape virtual full backup. The idea is simple - to allow users to back up forward forever incremental chains.

Thanks.
