Changing Storage Optimization

Post by cstemaly » Jun 13, 2013 1:58 pm

I have a several jobs that have been running successfully for quite some time. They use reverse incremental and have 4 restore points. I have been digging into how to improve my configurations, and discovered that I can improve deduplication by changing Storage Optimization to optimize for WAN target. Currently, the jobs are configured to use Local Target optimization.

I found the current line in the documentation:
Changes in compression and deduplication settings are not applied to the previous backup chains. The changes will take effect only when a new full backup is created.

With this in mind, how would I go about changing my jobs to optimize for WAN target with the least amount of effort? Should I just copy the data elsewhere and recreate the job?

You can just change the corresponding option in backup job settings and wait till the next full backup will take place: be it manual or automatic run.

Thanks.

When will the next full backup run?

My job is set to Reverse Incremental with no Active Fulls.

In this case, just perform manual full backup by right-clicking the corresponding job and selecting “Active Full” option.

Thanks.

[MERGED] Changing the Storage Optimization setting

Post by RaymondV » Oct 25, 2014 1:41 pm

Hi,

We use forward incremental backups with weekly synthetic fulls including transforms into rollbacks. I want to change the Storage Optimization setting from "Local" to "LAN target" (and perhaps later on to "WAN target) to save storage space on my backup repository. I understand that I need to perform a full backup for the change to take effect. Will a synthetic full be enough or do I have to run an active full? Some of our VM's are rather big and I don't want to have 2 or more full backupfiles per job on my repository.

Regards,
Raymond

Hi Raymond, active full backup should be triggered in order to apply these settings. Thanks!

What will happen if I have backup copy chained to this job ? After active full it will copy all the data again ?

Hi Ondřej, backup copy job will fail, since it does not support mix of block sizes. You'd need to perform manual active full for backup copy as well.

No, tape jobs are not affected by the block size change, since they operate with entire backup files.
