If it is the script itself: maybe you can cache the results of the script in some form? Have the script generate a text file, and the next time it runs, read it back in. Or run the script as a cron job independent of bacula store the output in a file, and then use that. If it is bacula itself that takes that long, then you need to find a better way to exclude these files. Is there a way you can move the inactive files into a different directory tree? If not: think about creating a completely separate directory for current files. Create links (hard or soft - hard links are probably better here) from that directory to the original current files. Exclude the full original data directory from the backup, and back up only this "shadow". > I've been trying to create a smart ruby-script that would build the optimal > list of all the old files/folders to be excluded, but it turned out to be > much > more difficult I initially expected. > > Is anyone else doing smth like that? > -- Kevin Keane Owner The NetTech Find the Uncommon: Expert Solutions for a Network You Never Have to Think About Office: 866-642-7116 http://www.4nettech.com This e-mail and attachments, if any, may contain confidential and/or proprietary information.
