Not sure if Timemachine is the operative item here or not..
We have two ReadyNAS, both Ultra 4+ on 4.2.22 with 5.4TB of storage. #1 is "active" and #2 exists solely to backup #1 via a Replicate system backup job.
BTW, that job is working very well and has been for months.
#1 has 2.7TB free, #2 only has 630GB free. From that I'm infering that the Replicate backup is slowly eating away at #2's storage. Why?
I thought that rsync had a facility to remove files that were removed from the source (#1). I'm wondering if this is somehow being "fooled" by the way Timemachine works.
There's a mac that backs up to Timemachine on ReadyNAS #1, which is included in the system backup to #2.
I'd appreciate some insight and also an answer to the question: Will the Replicate backup eventually fail when #2 is full?
Did you modify the number of backups to keep when creating the job? It will keep revision history so you might want to decrease it if you don't want so many copies (which ultimately take up space).
Thanks. I guess it defaulted to unlimited. I've set it at 30, which I'm presuming as a daily full system backup, means that I will have one month's worth of horizon. Is this correct?
Will it now proceed to remove the revisions older than 30? It's been running for a couple months, so there's at least 30-40 revisions to remove.
