594    =head2 Won't I run out of disk space?
595    
596    Of course you will... Snapshots and logfiles will eventually fill-up your disk.
597    However, you can do two things to stop that:
598    
599    =head3 Clean snapshort older than x days
600    
601    You can add following command to your C<root> crontab:
602    
603            find /backup/isis_backup -type d -mindepth 3 -maxdepth 3 -mtime +11 -exec rm -Rf {} \;
604    
605    I assume that C</backup/isis_backup> is directory in which are your snapshots
606    and that you don't want to keep snapshots older than 11 days (that's
607    C<-mtime +11> part of command).
608    
609    =head3 Rotate your logs
610    
611    I will leave that to you. I relay on GNU/Debian's C<logrotate> to do it for me.
