Retention policy

[jguillot]

Hello,

I have 6 repository with limited space.

Is it possible to have :
- 1st repository: first to 7th retention point (high speed)
- 2nd repository: 8th to 14th retention point
- 3rd repository: 15th to 21st retention point
- 4th repository: 30th day of backup (HPE Storonce VSA)
- 5th repository: first to 7th retention point (2nd copy, mid speed)
- 6th repository: first to 7th retention point (3rd copy, low speed over wan)

If yes, how please?

If not, what comes closest to what I want to do?

thanks in advance

It is not possible to split the chain the way you suggest but you can combine several repositories (1st, 2d and 3rd) as extents in a single single scale-out repository and use backup copy jobs to offload 2nd and 3rd backup copies, should address your needs.

Thank you for the answer,

So I will surely turn to SOBR but I have a few questions about this:

1) My 1st repository is composed of 6 SSDs of 400 GB and 16 HDDs of 1.2 TB

I would like to use tiered storage for this one, what is the easiest way to do it? ReFs with Storage space? If yes, how ? (system: Windows Server 2019)

Or then, I do 2 hardware RAID5 (1 for SSDs, 1 for HDDs) and can we create 2 repositories on the same server? (for example 1 on drive D: and 1 other on drive E).

2) The 1st repository is the fastest of the 3, how is the dispatch of backups on SOBR extends? The first backups will be fast and once the first repository is filled, the backups will be slower?

Is there a solution to optimize the speed of backups whatever the repository? hidden ?

thanks in advance

1. IIRC, Storage Spaces do not support RIAD. But yes, you can create different repositories even in adjacent folders on a single disk.
2. Please review this section for the description of data placement policies in SOBR.

Is it possible to have the latest backups always on the most efficient extent?

If you want the latest restore point to be always full, then you can select the reverse incremental backup method and specify that extent as the one storing full backups with Performance data placement policy.
