Hi all;
I've a question for a server not yet received.
The new machine is a 6800. Internal storage is a D240 (as a boot device) and a
3510 for data. In the 240 I have 3 x 73 GB and a DVD. One of the 73 GB disks
is redundant, so I'd like to use it for other things. If it matters, everything
will be running VxVM / VxFS.
First question: Can you fssnap a VxFS filesystem ?
If you can and if I stripe / mirror the 3510 to create 2 x ~365 GB mirrors,
can I
fssnap to the lone (extra) 73 GB drive on the D240 ? If I can, how many snaps
would the drive hold. I know the snaps are not the "data" in its entirety and
are merely a set of pointers -- one person suggested it would take 10% (in this
case 36.5 GB) for the snap. Finally, can anyone compare / differentiate
fssnap to Instant Image? -- Looking at this for backup windows. FWIW - we're
running II in a cluster and I know it's a mountable (separate) file system, but
fssnap seems capable of filling the gap here.
Thanks (I'll summarize).
Drew.
