I don't fully understand your setup, but there's a couple of ways to force a full backup: 1) In your normal 'daily' setup, run 'amadmin $CONFIG force' for each DLE. 2) Copy your daily config's amanda.conf and disklist into a new config (e.g. Archive) and change your dumpcycle to 0 in the new config. Then run that config. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
Re: Monthly backup
1. Have a backup run once a month on the 1st. We have a config which only does full backups and cron schedules it to run at the start of the month. 2. Only backup data 7 months prior to todays date based on -mm format. Do you mean only keep 7 months worth of data? Then only put 7 tapes in the rotation.
Re: Monthly backup
Well I have a folder lets say its called voice and in voice I have a bunch of folders in there labeled by date. Starting with todays date all the way back to 10-01-2005. I want to backup everything till may of 2006 for the. Then I'm going to delete all those files because I have them on tape. Then every month I just want to back up the next month so in this case the next month would be June then July etc. Steven Kurylo wrote: 1. Have a backup run once a month on the 1st.

I would create a symlink /path/to/link, pointing to /path/to/2006-04. Tell the backup to backup /path/to/link. When the backup is done, have a script which deletes /path/to/2006-04, then changes /path/to/link to point at 2006-05. Or you could have amanda backup everything, but use an exclude to block the most recent folders. Then you'd have to rewrite the exclude file regularly. I'm sure there might be a few other ways.

Perhaps an empty directory just for this purpose so it will be easy to find on recovery.

It could even run daily, check the if an archive is in the directory, if so, check the amanda index files to see if it has been backed up, and only do the deletions if all conditions are met. -- Jon H.

Re: Monthly backup
the folder name doesn't change. for example if I have folders 2006-01 2006-02 2006-03 2006-04 And I only want to back up folders 2006-01 and 2006-02. Is this possible? To back up certain folders and not others in a particular directory.

Monthly Backup Problem
Hi! I use amanda 2.4.3 to make Daily and Monthly Backups to Tapes :) Daily works fine. My Monthly Backup is designed to make a level 0 from all available Data - which will not fit to one tape anyway - so the plan was to not put in a tape, and have amanda backup everything to the dumps Partition. After that use amflush to move the data from the partition to tapes in several runs. But ... amanda uses the configured tape-size and excludes some backups even when not using the tape: xxx /data/xxx lev 0 FAILED [dumps too big, but cannot incremental dump new disk] What i do now ist using a dummy tape definition with the following entry length 9 mbytes, so that the backup is done in any case ... and changing the setup back to the correct value for tape operation. It works ... but I was wondering if there is an easyer way to accomplish this. Regards Kianusch

Re: Monthly Backup Problem
maxdumpsize 90g taperalgo largestfit Those are 2.4.4 options ... I run 2.4.3 ,,, But I got the idea :) Kianusch

I do our all-level-0 configurations this way, but for a different reason: it more fully packs the first tape. Since taping doesn't start until all of the DLEs have been dumped, the largestfit algorithm has all the data it needs to fill the tape as full as possible. If instead we let amdump write the first tape, largestfit would pick the optimum DLE ifrom among those available at the moment the drive became free/i, which would be suboptimal for minimizing tape usage. I'm not sure whether this applies to 2.4.3, since I don't know what (hardwired) tape algorithm it used. runtapes 1 maxdumpsize 90g That's what I did, but in 2.4.3, I presume one could get the same effect by increasing runtapes instead. In this situation, runtapes doesn't seem to have any direct effect on the actual number of tapes used :-/ reserve 0 taperalgo largestfit That's what we have. -- | | /\ |-_|/ Eric Siegerman, Toronto, Ont.[EMAIL PROTECTED] | | / It must be said that they would have sounded better if the singer wouldn't throw his fellow band members to the ground and toss the drum kit around during songs. - Patrick Lenneau
