Thanks it seems pretty nice to do it using a perl module instead a qx call. The problem to send the backup uncompresses its, they are mysql backups, it means, uncompressed, around 10 databases of around 1 - 1.5 gb. Compressed, 40 / 50 mb per databases. It worth using it compressed even the rsync protocol doesnt work at full power. In fact, im using the rsync protocol because its the easier way to do the backup against hidrive.strato. The other options like SCP and SFTP doesnt work very well. Im going to try it now!
