Best Practice for Son-Father-Grandfather rotation?

Everything about backing up to tape

The fact is that the Friday's VBK and daily VIBs in this case will be from different backup chains (backup chains from different jobs: VBK from the backup copy job, VIBs from the regular backup job) and you will not be able to restore from those VIBs without their corresponding VBK.

Yep, but your scenario seems to be different. If you want to have latest full restore point copied to tape on daily basis, then, you should switch to reversed incremental. This way, the copied restore point won’t depend on the other restore points, and you will be able to restore full VMs, using just one tape.

Otherwise, you can make something similar, using backup copy job, instead. Though, in this case, the full restore points copied to tape will be not the latest one, but rather a 4-day old one.

Also, I don’t recommend using off-site backup copy job as a source for tape jobs, since, in this case, the backup data will be copied to tapes from remote location, affecting seriously performance rates.

Thanks.

Thank you very much, Alexander and Vladimir,

I appreciate your support! But I think I'm a little bit confused about the whole topic. :?

If I want to use the VIB files of my ordinary backup job (which are quite small) then I have to backup first the whole VBK to stay in the same backup chain... correct? This seems to be easy... but the synthetic fulls are also in the same folder located.

I think I should give it a try and experiment with the Reversed Incremental.

Aren't there any other VEEAM customers which are trying to backup to disk and to tape?

Correct. Each VIB in the chain depends on all previous VIBs and the corresponding VBK file, be it either active or synthetic full.

So... what is the best way (in youre opinion) to get backup-to-disc-to-tape (with GFS scheme on tapes) up and running? Which backup method (reverse or forward incremental) would you prefer / advice?

I'm stuck at this point of my backup strategy plan and try to figure out what would be the best way.

Thanks in advance.

It depends on your desires. If you want to have independent full backup copied to tape each day, then, stick to reversed incremental. Otherwise, if you’re more interested in copying incremental backups, then, forward incremental should be the way to go.

Thanks.

Well I think that my desires are changeable if someone tells me "that way you can save a lot of tapespace and youre backup is absolutely safe".

I try to figure out which way is recommended and the best because my approach seems to be wrong or led to a never restoreable backup to tape in case of emergency.

Thanks.

There's no universal approach, you would always have to deal with peculiarities of this or that backup method. We tried to give you recommendations based on your specific requirements, however if your requirements tend to change from time to time, you should adjust your backup strategy correspondingly.

Thanks Alexander.

I'm going to read the B&R Manual again and try to figure out which might be the best solution approach for my environment. Maybe I'll understand the manual this time better. :roll:

Thanks a lot to you and everyone who participated in this thread.

Is there any plans to build in a Son-Father-Grandfather tape approach in a patch going forward in the future? We have it for backup to disk, so I can't imagine it would be out of the question?

Hello everybody,

@mFrenzel: Maybe we have the same approach. I am seeking for the right GFS-backupconfig with veeam. Which config have you figured out?

d.popov wrote:Yes, this feature is in our longer term list.

Very good idea. I want to support the other customers who need this d2d2tape feature with GFS

Thanks

Hello,
Please, review this scenario for GFS as a workaround:

Daily Cycle:
Create a first "Daily" media pool with 6 days retention period.
Create a "Daily" backup to tape job pointed to the “Daily” media pool. Schedule it to run 6 times a week (Mon,Tue,Wed,Thu,Fri,Sat)

Weekly Cycle:
Create a second "Weekly" media pool with 4 weeks retention period.
Create a "Weekly" backup to tape job pointed to the “Weekly” media pool. Schedule it to run every Sunday of the week.

Monthly Cycle:
Create a third "Monthly" media pool with 12 months retention period.
Create a "Monthly" backup to tape job pointed to the “Monthly” media pool. Schedule it to run monthly at every last Sunday of the month

With this rotation scheme. Does the monthly job supersede the weekly, or will Veeam run both jobs and backup the data twice on the last Sunday of the month?
