The script creates backups in the hot_backup/ folder but doesn't delete old backups. So if you've run the script four or five times, then 17G would be reasonable. Try this:
Code:
cd /path/to/your/hot_backup
du -h --max-depth=1
I'm guessing you get something like this:
Code:
4.25G ./2005-12-13_13-33-27
4.25G ./2005-12-14_15-29-20
4.25G ./2005-12-14_15-32-32
4.25G ./2005-12-14_16-22-23
Each directory inside of backup_dir is named with the date and time that the backup was started. For example, the first backup was started on December 13, 2005 at 1:33 PM.
If you need to clear some space, you can delete the older backups like this:
Code:
rm -rf /path/to/your/hot_backup/2005-12-13_13-33-27
