Sorry for the simple question, that’s no doubt been asked and answered before…
Today we have VCC for our off-site cloud backups, and the immutability is provided by the “Insider protection” which in short means we pay for the privilege but we do not need to worry about disk space consumption over and above our actual backups.
For lower cost we’re considering object storage, probably Wasabi, and we’ll want immutability there also. The thing I need to be sure of, is the disk space required. I am not sure if the copy jobs would have a specific backup mode, but with incremental, if they’re immutable, you’re previously overwritten backups are kept for longer? Disk space could be double what you have before?
Thanks in advance for any insight on real world disk space requirements. Today, 27TB approx. is our VCC repo and as I say, the immutable data is retained at a fixed additional cost so we don’t know the size of that.
