Compressed backups

Hi, Does delta (incremental) backup compress backups on the backup repository? Is there a way to enable this to reduce the amount of data to transfer?
Thanks. -

Thanks.Delta, by definition is compressed to changes only, there has been some discussion on the forum about how effective this is when comparing Linux and Windows guests and how much the delta's are different.
Additionally, you can enable compression within the advanced settings under a given backup, see below for an example.

@DustinB
I couldn't see the Compression field under "delta backups" but now I see it for full backups. I guess then compression is not available for delta backup because it would screw up file merge when retention has been reached. Is this right? -
Compression is enabled by default for incremental backups.

@olivierlambert Thank you. Does this apply to the key backup as well as the increrments?

FYI, you should create a remote with "Store backup as multiple data blocks instead of a whole VHD file" to enjoy better backup perf with compression (IIRC, we use brotli). Every info we can compress will be compressed.

@olivierlambert Thanks. I'll do that.
