Hi Mark,I've written a nagios shell script to check my pools in the way you describe. I also remember that Arno Lehmann did something similar in perl (it is distibuted with the bacula sources)

Is there any way to have bacula predict how many volumes will be needed for the next night's backup?My goal is to make sure that the autochanger is always loaded with enough tapes to handle the next night's backup, without changing tapes every day. I'm interested in having bacula notify me in advance that it guesses that the following night's backup will require "N" volumes. I don't want to run "estimate" for each client (which is a time-consuming and resource intensive action), and then sum the results. It would be great if bacula made use of information that's in the database to get the average of the sizes of the last "X" backups of the same level that's scheduled for the next backup (ie., full, incremental, differential) for each client, and then added a user-defined fudge-factor (maybe 10%) to guess at the size of the upcoming backup for all scheduled jobs. For example, most of our non-full backups are under 100GB for all clients combined, so our autochanger can run for a long time without manually removing full tapes and putting in new ones. However, full backups can be anywhere from 40GB to over 2TB (depending on the client). To reduce contention, full backups are set up with a staggered schedule--each client does a "full" on a different night. It would be nice to get some warning from bacula that the next night's backup will "probably" take 6 volumes, so that I can make sure the enough empty (or over-writeable) tapes are loaded.Any suggestions about scripting such an "early warning system"? I'm thinking of something like:----------- bad pseudo-code --------------------------- foreach $client sqlquery("Get list of clients scheduled to backup tonight") { $backup_level=sqlquery("Get level of next backup for $client"); $size=average(sqlquery "size in GB of all backups for $client of $backup_level"); $predictedsize=$total + $size; } $predictedsize=$predictedsize * $fudgefactor; foreach $volsize (sqlquery("Select VolumeSize in GB where VolumeStatus='Full'")) { $volsizetotal=$volsize + $volsizetotal;$volcount++; }$average_GB_to_fill_volume=$volsizetotal/$volcount; $volumes_needed=$predictedsize / $average_GB_to_fill_volume; roundup($volumes_needed); print "There will be $volumes_needed needed for tonight's backup"; ------------ EO bad pseudo-code ------------------------------------------- Thanks, Mark ---- Mark Bergman [EMAIL PROTECTED] System Administrator Section of Biomedical Image Analysis 215-662-7310 Department of Radiology, University of Pennsylvania http://pgpkeys.pca.dfn.de:11371/pks/lookup?search=mark.bergman%40.uphs.upenn.edu The information contained in this e-mail message is intended only for the personal and confidential use of the recipient(s) named above.
