I have a ZFS volumn of 3 HDDs in RAID0(1TB*3). I want to add a 3TB drive for periodic backup. How can I set up periodic snapshot to store the backup on the new drive?
1. Is there any special requirement for the 3TB drive? i/o performance, filesystem etc.?
2. Is it possible to use a disk smaller than 3TB for snapshot if the actual used space is way less than 3TB(actually less than 1TB)?
3. How much does snapshot process impact the performance? I use the ZFS volumn for vSphere iSCSI and CIFS.
4. Any concerns with this method? RAID0 probably should never be used but the data is not that critical. With $ constraints, this is the best way I can think of. Any suggestions?
Thanks.
