Change all your Veeam backup jobs to the new forward forever-incremental

When you upgrade Veeam Backup & Replication to V8, you have available the new Forward forever-incremental mode for your backups. This is the default method for all newly created jobs, but the alredy existing backup jobs are not changed, because we do not want to change the user experience or create issues to I/O profiles, backup windows and such.

If you want to leverage the new method, you simply have to edit your existing jobs and change their configuration. If it’s already a forward incremental job, you simply have to remove the scheduled weekly active or synthetic full. If it’s a reversed, you need to switch to the new mode. In any case, the existing retention will be preserved until it’s expired, and afterwards the new backup chain will be the only left into your backup repository.

But what if you have a large amount of jobs, and you want to reconfigure all of them? The manual edit could be cumbersome and take time, and also you risk to forget some of the jobs.

We have some great guys at Veeam, and from time to time they create some neat scripts and tools. This time, Preben Berg created this great powershell script, that will take all your existing forward incremental backup jobs and reconfigure them to use the new forward forever-incremental mode. Just run it against your Veeam Backup & replication server, and all your job will be reconfigured in few seconds.

Note that reversed incrementals will not be impacted by the script.

Great job Preben!

  1. Luca, thank you very much, I’m going to be upgrading from v7 to v8 to take advantage of this new mode, it’s nice to know this is very painless!

  2. Hola Luca. If I transfer a reversed inc. Chain into forward incremental forever. Will the whole reverse chain persist until the forward Chain has reached the wanted number of restore points? Does the change to ff inc create a new full backup file or will it use the reversed inc full which is in front of the chain? You can guess what’s my problem.. The rev. inc chains are configured are from restore point view optimized to use as much space on the repository as possible..

    • Space consumption of reversed and forever forward is exactly the same, so no issue in moving from one to the other.
      And yes, retention will take care of removing old restore points and use the full backup of the reversed incremental as the starting point for forever forward.
