OK, last week we replaced the backup drive on the server. This week the main OS drive is getting cloned onto a new drive. This will bring a larger down time. Probably about 4 hrs, if things get complicated maybe a full day.
I'm also making a full backup right now, which will go on for a few hrs. I nice'd the process, but that may still make for a very sluggish OB today.
Once the 2nd drive is replaced we should be good for a while longer and enjoy more storage space
Thanks for your patience.
