Re: Strategy for a backup of Video EEG data...

Oh, simple: it is 80+TB of (uncompressable) data, so a full can cost (opn a
single LTO9 tape) some weeks of backup... and the same tape is needed to do
some other day-by-day backups.

So my idea was to do a 'incremental fileset' backup, adding to fileset the
folders one by one, to reduce backup time to a decent amount (i can stop
day-by-day backup by some days, if needed).

Thanks for all other suggestions.


I'm thinking on that:

 + define a 'full' pool, with a job and a fileset with 'Ignore FileSet Changes = yes'
   where add all the exams directory apart the current one

when the archive backup get done:

 + create a 'incremental' pool where doing incremental backups of all
   the exam folder including current (we are thinking about one a month).

when a new exam folder get created:

 + clean all jobs on 'incremental' pool and do an incremental on the 'full'
   pool, so we have the just archived exam folder not scattered on dozen of
   incremental...

Too complex?!
