Hello,

Considering a PC server running FreeBSD with 4 400 GB hard drives attached
to a hardware raid controller doing raid-5.

So this will present itself to the OS as a 1.2TB filesystem.

Any comments on taking one or multiple snapshots of a filesystem of this
size ?

Given current disk capacities, I would not exactly consider this 1.2TB
filesystem a "large" one ... any comments on say ... a 6-8 TB filesystem
and making one or more snapshots of it ?

Assume they are marginally busy - perhaps a 5-10% data turnover per day...

Thanks.
