Current problem – seeking solution (backup related)


Let me expalin a little about a problem I am trying to solve. This relates to backups using Backup Exec 10 and 11. I am hoping to get some feedback and ideas on a solution, your comments and ideas are welcome. Please feel free to post to the comments on this article.

First, we have servers all over the place and back them up locally when possible. So each major location has a consolidated backup server with over 1TB of hard drive space and utilizes a backup to disk strategy for the daily backups, and then we have a separate archive to tape job which puts the B2D files onto tape. We keep 3 days worth of backup to disk files on each backup server, using media set controls with a overwrite protection period of 2 days so we only ever have 3 days of backups in each media set.

Jobs are configured with backup to disk folders to keep the media in. Now the issue comes as our storage grows, we are backing up more and more data. Keeping 3 days worth of data on the server gets harder and harder. Not to mention we also are currently backing up 3 days worth of backup to disk files to tape each day, which eats through more than one ultrium tape per day.

The goal I am working towards is being able to keep 3 days worth of backup to disk files on the backup server (idea is to have quick access to restore media 3 days back in case something important needs to be restored) but we only want to backup 1 day at a time to tape, so we don’t waste tape storage and have some crazy confusing tape rotation schedule. We use an autoloader with 24 tape capacity, and are having difficulty in maintaining a good predictable rotation.

So does anyone reading this have any suggestions for being able to keep 3 days worth of backup to disk files on the server, but support backing up only 1 days worth of files at a time to tape? Currently the backup to disk folders are created and named after each server.

I also want to find a way to prevent having to use third party software to keep the backup to disk folders cleaned out. Sometimes the B2D files don’t get re-used for a while, they are protected, but don’t get re-used and just sit there taking up space and ultimately eat up valuable hard drive space for nothing. I had been using some external software to clean out files older than 3 days from these folders.

All suggestions are welcome.
