Kopia repo - enable compression

[Lyndon-Li]

Compression is not enabled for Kopia repo, after several releases with Kopia, we can try to provide an optional configuration to enable it.

This would add cpu requirements I assume

Yes, so it is configurable

Velero creates the repo per namespace but at the moment the setting can only be global. There can a lot of parameters to customize for the repo, we may need to have better overall thinking about the workflow to decide whether we should allow velero to connect to a repo server that is already configured.

Besides saving storage, another case that compression could help:

• Users have object store in the public cloud
• The source cluster is on-premise or in a different cloud from the object store
• Then whenever backup/restore/repo maintenance, large data is uploaded/downloaded, so the fee to transfer data is considerable
• Compression helps reduce the size of data to be uploaded/downloaded so helps to reduce the fee

We need compression, the current backup in our cluster is too large.

Some files, such as text and database file in pods, would be better compressed.

We'll need a design to determine how to expose these settings. Given we wanna focus on the datamover enhancement in v1.15, this will be kept in backlog and we'll revisit it in future planning.
