Scalix backup: Part 1- Users Message Store
If your server setup does not support creating file systems snapshots rsync-ing the message store is not the best solution because you may have to keep Scalix off for a long time. So you will need another way for saving data.
Based on scripts found on Scalix Community forums I created a small backup script which is more appropriate for my needs.
It will keep copies for every day of the week, so be sure you have enough free space on the backup volume.

The script uses omcpoutu which copies a user message store into a file. During the backup users cannot access the server, so it’s better to run it when users usually don’t access the server. I set a cron job to run it at 1 AM. It takes about an hour to complete, for 11 users and 5 GB of gzip-ed data.
