Everything about backing up to tape

Hi Dima,

We have 4 of those media sets with a retention period of 4 weeks so we can rely on daily revisions of the user's files for about a month. After that we have weekly data for one quarter and monthly data for one year.

Our backup chain is like that:
- Saturday (1st): Monthly 1 (full)
- Monday to Friday: Monday 1 to Friday 1 (incremental)

- Saturday (2nd): Weekly 1 (full)
- Monday to Friday: Monday 2 to Friday 2 (incremental)

- Saturday (3rd): Weekly 2 (full)
- Monday to Friday: Monday 3 to Friday 3 (incremental)

and so on...

It’s true for now GFS media pools (and job targeted to the GFS media pool) supports full backup only. Can you clarify how long would you like to keep these incrementals in conjunction with GFS rotation schema? Thanks.


The incrementals go to tape just in case we suffer a storage failure at our DR site. That way we still have incremental restores to meet RPOs for the week.

So to answer your question, the incrementals are kept for about 1 week by RPO, however in reality they generally stick around for about 2-2.5 weeks before they get overwritten. The media pool is about double the size it needs to be for an average week.

Edit:
Our GFS rotation looks (should look) like this:
Grandfather backups: Monthly, 1 year retention, full backup only, written on the last Saturday of the month (backup taken on last Friday of the month)
Father backups: Weekly, 4 week retention, full backup only (written on Saturday, backup taken on last Friday)
Son backups: Daily, 1 week retention, incremental only (incrementals from father backup above until next father job)

Hi guys,

For now it sounds like we should add fifth media set and call it daily to keep the incremental backup. May I ask what then supposed to be a schedule for backup to this media set – somewhat similar to ‘as a new backup file appear’ option or just daily at XX time of the day? Thanks.

Personally I'd love to see an "as new backup files appear" option - a regular schedule would also be good, but that'd be my first choice.

Both choices would be great but usually I use a simple daily schedule. And please open GFS media pools for file to tape jobs, too.

Count me as one to request this sort of feature as well. We currently need to have daily incremental backups to tape with a 1-2 week retention. Currently, managing this with the regular media pools, because of our expanded GFS needs is a nightmare.

Hi all,

I'm testing GFS tape offload in our test lab, and I have some questions..

The setup:
1 backup job with some VM's, running Monday till Saturday (not on Sunday).Incremental backup, with an active full on Saturday.
Backup job starts on 6PM.

1 GFS Media pool With Weekly and Mothly tapes (no quarterly and yearly).

1 Tape job for GFS with weekly schedule on Sunday, and monthly the first Sunday of the month.

Test Results

So I have a full backup running on Saturday, and after that job, on Sunday 0:00 GFS Tape Offload starts.
As the last backup in the chain is a full backup, I thought Veeam would take that full restore point and put in on Tape (as this Sunday was the first Sunday of the month, a Monthly tape).

But what I see now, is that the tape offload job started on Sunday at 0:00, but It gives this messages:
Code: Select all
7/02/2016 0:00:10 :: Building source backup files list started at 7/02/2016 0:00
7/02/2016 0:00:13 :: No GFS candidate for Monthly media set was found for today, waiting


Very strange, because there is a VBK file that was created on 6/02/2016 6PM....
Then after 24h, I got this message:

Code: Select all
8/02/2016 0:07:27 :: No restore point for 7/02/2016 is available for virtual full backup, using previous restore point for 5/02/2016


And then a virtual Full backup is created based on the latest incremental backup, the one of Friday evening...

So instead of using my active full bacup to create the GFS Tape, it creates a virtual full backup, based on the restore point created the day before the full backup...

What I would like

What I would like is a GFS tape job, where I can specify at what time it should start (not on 0:00 automatically), and that puts the latest backup on tape. If the latest backup on disk is a full backup, just take the VBK and put it on tape. If the last backup is an incremental backup, then create a virtual full backup and put this one on tape (but based on the LATEST backup)...

Hi, Bert,

Wasn't the GFS tape job added after active backup had been created on Saturday?

If not, the described behaviour doesn't look expected, as the latest restore point (in your case .vbk file) must have been archived to tapes.

Thus, we'd appreciate if you open a ticket with our support number. And post ticket's number here, once it's opened.

Thanks.

Hello,
I had a similar situation.
Daily backup to disk scheduled at 2/12/16 9 PM, reversed incremental, stopped successfully at 9.51 PM, new VBKs in the repository (per-vm backup files).
GFS backup (Weekly) started 2/13/16 at 00.00, stopped with warning after 24 hours, despite the presence of full backups.
From the Guide "The job starts at 00:00 at the scheduled day and waits for the source job to create a full backup. If no full backup appears in 24 hours, the GFS job synthesizes a virtual full backup from the most recent restore point available."
But if the vbk is already present I think that Veeam doesn't wait 24 hours.
What does it mean the warning "Partial backup detected for restore point created on".
I uploaded the job statistics here:

I have checked the case and it seems that the answer provided by our support engineer is slightly wrong. As the described behaviour is neither intended, nor expected. We'll keep investigating it further.

Kindly, open your own case and make reference to the case number 01691640 and this thread.

Both support and QA teams are about to take a look at the provided logs. I'll update the topic should something interesting be found by them. Thanks.

[MERGED] : Tape Backup - GFS

Veeam Logoby Max Dembo » Thu Feb 18, 2016 9:15 am

Hello,
Veeam v9, Case 01698894.
Daily backup to disk scheduled at 2/12/16 9 PM (friday), reversed incremental, stopped successfully at 9.51 PM, new VBKs in the repository (per-vm backup files).
GFS backup Weekly started 2/13/16 at 00.00 (saturday) , stopped with warning after 24 hours using the full backup created saturday night, despite the presence of full backups friday night.
From the Guide "The job starts at 00:00 at the scheduled day and waits for the source job to create a full backup. If no full backup appears in 24 hours, the GFS job synthesizes a virtual ful backup from the most recent restore point available."
Question 1:
By design a tape backup using GFS that starts saturday at 00.00, can use a full backups created friday night or can use only full backups created during the 24 hours of the scheduled day?
Question 2:
What does it mean the warning "Partial backup detected for restore point created on".
I uploaded the job statistics here:

Max,

Kindly, avoid posting about the same issue in multiple discussions.

Can use a full backups created friday night?

This.

What does it mean the warning "Partial backup detected for restore point created on".

Meaning not all VMs present in source backup jobs have been copied to tapes. Sometimes we might throw this warning by mistake. (considered as a bug and will be fixed in Update 1)

Anyway, keep working with support engineer on addressing the said problem.

Thanks.
