SOBR / object storage: active full storage usage

Post by apolloxm »

Base on my testing, for the first time, both SOBR copy mode and directly to object storage with full data to cloud. If I run an active full again. sobr copy mode will create a full in the performance tier but just offload the changed data to object storage(it took less time and used less space ). however, for directly to object storage, it will be created another full size (you will see another full size in the object storage and took another full time)
Can you tell us what is the difference behavior between Backup copy job with SOBR copy mode to offload the data to object storage and just offload the data directly to object storage with Backup copy job? also, Can you also clarify the retention policy between SOBR with copy mode and directly to object storage with a backup copy job?(for example, if set the retention policy to 14 days in the backup copy job, enabled the GFS and keeps weekly to 2. keep immutable to 14 days. what will be happen? )

Hello Apollo

I split your question from the other topic. Please create new topics if your question is different than the one from the topic author.

Correct.
Can you tell us what is the difference behavior between Backup copy job with SOBR copy mode to offload the data to object storage and just offload the data directly to object storage with Backup copy job?
A capacity tier and an object storage repository are different types of backup targets. A direct backup copy job to an object storage behaves similar to a backup copy job to a Windows or Linux repository. If you create an active full, entire space for a full backup will be used. If you don't enable active full, it will be a forever incremental backup chain. Synthetic full is not available on object storage repositories.
also, Can you also clarify the retention policy between SOBR with copy mode and directly to object storage with a backup copy job?(for example, if set the retention policy to 14 days in the backup copy job, enabled the GFS and keeps weekly to 2. keep immutable to 14 days. what will be happen? )
In both cases only changed blocks will be offload. On object storage repositories, GFS is only a tag. Example: On a Saturday, the backup job will store the new incremental backup to the object storage repository. Because you have enabled weekly GFS retention on Saturday, this incremental restore point will be marked as a weekly backup. Veeam will retain all objects belonging to this weekly restore point at least for the retention period you have set up in the job settings. If a new restore point is written, retention time of those objects will be extended accordingly to the retention settings (GFS, short term).
It works similar in the capacity tier. A weekly GFS restore point offloaded to the capacity tier will be tagged as a weekly. All belonging objects will be retained for their retention time.

Hello Fabian,

Thanks for your reply!
Can you give me an example that would be better for understanding. Thanks!

Can someone answer my question with this example?

Hi Apollo

Retention: 14 days
GFS: 2 weekly
Immutability: 14 days (+10 days block generation)

With such configuration, you will have 14-21 restore points on the capacity tier.
Obsolete Objects of outdated Restore points can not be deleted because they are still immutable (14-24 days).

The same is valid for direct backup copy to object storage. Immutability period must be lower than your retention period, if you want to be sure that objects are deleted according to the configured retention policy.
Can you give me an example that would be better for understanding. Thanks!
For which part? The one I just have answered?

Hello Fabian,

Thanks for your reply! according to another topic posted, your R&D said that "this is a internal background process that no one should care and not change (it just works and optimizes things for you). Set the immutability to the amount of days you need it and you are done." this made me so confusing
