Running NE 5.0.12 on CentOS 4 x64 2xdual-core Proc 32 GB RAM
I'm working on a plan to upgrade my server box to something that will last me a while longer. The primary storage will be moving to a SAN and the machine will get a big fat boost of RAM + CPUs.
Will be: Centos 5.3 x64 2XQuad-Core Proc
Problem comes in when you get to backups. Currently, from what I can tell, the /opt/zimbra/backup directory is approx 2-2.5 X the size of everything else put together.
If my store were to grow 100%, I'd be looking at 5 TB of space required for backups. I expect this to happen in the next year or so. The ext3 filesystem has an upper limit of 8 TB (subtract out the space the FS needs just for itself).
So here's the question: How do I get my backups to work if I expect them to be over 8 TB?
