I would suggest to use different partitions for your OS and another big one for your backup data. In fact, if you can use two smaller disks in RAID 1 for the OS and leave your two RAID 5 for the backup data alone, that would be even better. This way you can both a) install the OS without any problem and b) prevent a *very* long fsck in case the machine crashes and your 7TB partition is broken beyond the background fsck process. Once you have the OS installed on the smaller partitions, you can then use gpt(8) to create your 2TB+ filesystems. YMMV. We use a scenario quite identical as what you're trying to do. We use a few ports to do so, like sysutils/rsnapshot and shells/rssh with rsync and OpenSSH along with an encrypted backup volume and OpenPGP to encrypt the tapes. For VMWare images, we use sysutils/rdiff-backup. It works very well for 100+ mixed FreeBSD, RedHat, Ubuntu and AIX hosts. If you need any help with the backup setup and all, just ask, I'll send you the howto.
