So we have two sites… one media agent at each site. Each site has a Primary backup to that sites’ MA with a secondary going to the other site. It’s been this way for years.
In THEORY, with each site writing to itself and copying to the other, using dedupe/compression… one might think both sides would look roughly the same - as it’s the same “stuff”. However, one site is ~290TB while the other is 440TB and growing.
I’ve talked to support to find out if there was a way to reconcile this difference and, while they were extremely helpful, it seems that life’s answer is “with dedupe and compression, you’re not guaranteed the same size when these things are involved. You’re just going to have to purchase more space at the larger site”.
Don’t get me wrong - we’re backing up more than a petabyte of data on each site, but it seems like one’s just far less efficient than the other.
Has anyone else faced this situation, and how did you deal with it?
