Disk space used by backups

Hello

I started using the automatic backup script for The dude found on this forum: http://forum.mikrotik.com/t/script-for-making-automatic-dude-backups-remotely/30447/1

My backup file is about 37 Mb (.xml). I installed the dude inside RouterOS with 1 Gb Disk Space. I run the backup script every day and yesterday I found that the disk space of my mikrotik box was just 35 Mb free and the backup script failed. After I restarted the system, the free space was again more than 900 Mb.

What I see is that after every backup is run against the dude server, the backup file generated stays there (in some private location, as a cache or something like that)… I can’t find the backup file generated so I can’t erase it… after some days, the disk is full and I can’t backup anymore.

Does anyone know how to erase these old backup files (.xml) from the internal cache so I can free the space after every backup?

Thanks for your help and best regards.
