Re: How to compare 3 lists

[grizzley]

Should the date-of-creation be the same in all three lists or not?

Is snapshot1 named 'snapshot1' in all lists? Then just read one list after another and for every list search for word 'snapshot1', 'snapshot2', etc. without even comparing lists.

Yes, zfs allows you to use a tunnel (we use mbuffer) to send snapshots between systems meaning you can create an independent mirror but without the performance penalty of synchronous systems like drbd (the downside is that you may use changes)..

Sorry, I have no idea about zfs and therefore no idea if this is 'yes' for timestamp or 'yes' for second question.

Should have clarified.. It's a yes to both, all the snaps are identical on all the systems (name, date etc.). I'm just getting to grips with Perl so I'm going to play with the suggestions (it might take me a while though :-) ). Thanks.
