[OmniOS-discuss] Backup script (one local, multiple remote snapshots)

[Matej Žerovnik]

I did have a look at it during the weekend. Nice tool and easy to use.

It did, for some reason, kept too many snapshots (my retention was 1min=>1min on SRC and 1min=>1min,10min=>10min,1h=>1h on DST). What I got was 2 minute’s snapshots, 2 10 minutes’s snapshots and 1 hourly snapshot on the DST. Is this normal?

Is it possible to not copy the whole dataset/zvol to dataset/zvol but unstead, do it like zetaback, copy dataset/zvol to file on dst?

Thanks, Matej
