If you are taking the backup via script, you may need to delete your old backups on regular basis to avoid disk space issue. The following command will remove directories from “/home/mydirectory/” which are older more than a month:
for i in `find /home/mydirectory/ -maxdepth 1 -type d -mtime +30 -print`; do echo -e “Deleting directory $i”;rm -rf $i; done
/home/mydirectory/ = Replace with actual path
maxdepth 1 = list only files/directories in 1 level from main search directory
-type d = list only directories
-mtime +30 = Adjust your days here
-print = print out list
