Re: Does amrecover automatically use "unflushed" files on the holding di

Does this also suggest that one could set a 1TB hard drive to be theholding disk and only write to that, i.e., never use flush to 'tape'out the data. If that is possible, and the holding disk can be usedas a 'fifo' type storage system, might that not be the ideal HD basedbackup system as opposed to using chg-disk?

I assume the overwriting of older backup data would be the issue,which is why I thought of a fifo type storage. This way one couldkeep as many tapecycles as the drive could hold and just lose onewhen more data is backed up.

I currently do not use a holding disk and write directly to theexternal HD. The result of that is that each disklist is only doing asingle backup at a time (sequentially). As long as the network is notthe bottleneck, this is not an ideal way. Using multiple disk listsand amdump instances could do the trick, but then you get more andmore report emails and slots to maintain (when things go wrong).

Am I being stupid doing it this way? Does somebody have a bettersuggestion as to how to back up 11 different boxes to one server?

   A quick question.
Suppose you run some level 0 backup (GTAR method) with amandaand leavthe files on the holding disks until there is enough files tofill a
   tape and run amflush. Say this takes 5-6 working days.
   Now, if, after 3 days, I have to restore something that has been
dumped on the disk on the first day and run "amrecover" on theclient
   and "setdate YYYY-MM-DD (today - 3 days)"
Are the holding disk files "indexed" ? Will amanda use themand not
   ask for a tape when comes the time to extract ?
Quick answer: yep!


And as an added bonus, its faster than restoring from tape.
