had the same situation. Our problem was that the day we chose to compact the incrementals (saterday) was NOT in the schedule for the job (only mon-fri).One we added satuday problem was solved. Kind of strange however that veeam lets you create the job this way. Would be nice to have a check implemented that avoids this kind of errors.

Help!

We have exactly the same backup! Where can i setup the day to compact our backups? At this moment i configured 5 restore points and backups run from mo-fri!

You need to pick up any day from Monday to Friday using Advanced Settings of the backup job. See our User Guide (page 62) for additional instructions.

I See.

By default Saturday is configured as the day the backups should be compacted. My backup runs tonight at 18:00 and could be done before or after 0:00, so should i configure wensday or thursday as day to compact the backup data?

If your job starts on Wednesday, then you should choose Wednesday to transform your backup chain, as only job start time matters here.

Vitaliy, is there a way to perform a 'compact' of the backup data by using commandline?

Re: Deleted VMs Retention Period

Veeam Logoby habibalby » Wed Nov 16, 2011 5:14 am

[merged]

I'm still a bit confused on how to configure the retention policy. Before Veeam backup, I used to use the Backup Exec, Weekly Full, Daily incremental and Monthly Full Backup.

Now I do have Veeam as well as Backup Exec, What I want to achieve is to have Veeam to run Weekly as Full Backup and starting from Sunday towards Thursday as incremental. Backup Exec will backup the VBK and VIB files on a daily basis.

For how long shall I configure the retention policy? I want to have the full backup and daily backup of veeam to be backed up by Backup Exec for Off-Site storage and to save space as well when the retention policy over.

Thanks,

Hello Hussain,

Basically, there are two backup modes available: reversed and forward incremental. In both modes you should configure retention policy to keep 7 restore points, but the number of roll backs located on the disk will vary based on the backup mode you've chosen. See the details below:

Reversed Incremental:
With retention policy set to 7, you will have 1 VBK file (the most recent backup state) + 6 VRB files (incremental changes)

Forward Incremental:
With retention policy set to 7, you will have 1 or 2 VBK files (full backups) and up to 14 VIB files in total (daily changes) during two weeks. Here is a good explanation why it works this way, check it out.

Thank you.

Hello Vitaliy,

So, the Reversed Incremental turns to be a better approach when selecting Backup-To-Disk and Then Backup-to-Tapes. Because this reducing the number of files needed on disk and keep only the retention files needed on disk for Restore From Disk Purpose.

For my needs, it's the best to select this approach. I'll be doing the following;

Fri - Full Backup Veeam.
Sat Full Backup of Symantec.
Sun-Thu Revered Incremental of Veeam Backup
Sun-Thu at night, Incremental Backup of Symantec.

This will give me a 7 restore points I can go back to till it starts the backup for the next day. If the backup starts and deletes the previous day backup, I can get it only from tapes. Will this be good to go?

Thank you,
habibalby

With reverse incremental, the VBK is always the most recent backup, so if you're going to tape every night, you have to backup the entire VBK file to tape each not. I think this is not what you want.

For tape backup I would recommend using forward incremental backup mode, that would allow you to drop only incremental backup files to tape everyday.

Hi,
I have a problem in selecting the Forward Incremental in regards with disk space. I set all the jobs to;

Retention Policy:

Restore Points to keep on disk 6 Days.

VM Retention:

Deleted VMs data retention period 6 Days.

Active Full Backup:

Weekly on Friday.

This leaves with 2 VBK files and 5 VIB files for the daily incremental from Sun-Thursday. and today it will start running as Incremental till thursday which I'm already lack of disk space and I don't know what to do.

How can I configure the jobs to have?

1 VBK File of last Full Backup "Friday"
5 VIB File of Sun-Thur

I want to do this configuration because I want to run Symantec also in the same manner, tapes for daily contains VIB incremental backups of Veeam and other set of tapes for Weekly and Monthly contains VBK Files of veeam.

Would this be do achievable?

Thanks,
habibalby

With Reversed Incremental Backup will not allow me to drop only the VRB "Incremental Files"? Symantec Backup will run full and will Reset the Archive Bit on the files, so when Archives Bit reset from the last Full Backup, and on Sunday Symantec Backup runs as Incremental it will includes only the VRB files of the Veeam!!! Am I write? or it will include also the VRB files and VKBs?

Thanks,

Hello,
I re-configured one of the job from Incremental 7 Retention Days to Reversed Incremental 5 Retention Days. I ran the job for 5 times and it deleted all the VIB files and created 5 VRB Files including 1 VBK File.

Does this imply to my logic of the number of the Retention Days on Disk?

You need to have more space if you want to proceed with forward incremental backup mode.

With forward incremental backup mode you will always have more than 1 VBK file, so this is simply impossible to achieve with the forward incremental backup mode.
habibalby wrote:With Reversed Incremental Backup will not allow me to drop only the VRB "Incremental Files"?

With reversed incremental, incremental data is rolled into the full backup (VBK) file during each job run, so you would have to offload the full backup file (VBK) to tape every day, because this is the file that will contain your latest VM state.
habibalby wrote:Does this imply to my logic of the number of the Retention Days on Disk?

VRB (incremental) files created by reversed incremental mode do not contain recent VM changes, as this data is stored in VBK file.
