To expand a lot on vbe and RudiC's posts:

Does the first cron job ALWAYS complete in less than two minutes? If cron starts another job after two minutes and the previous one is still running, things will become awful rapidly.

Also: You are not checking either filesize or mtime of the .cdr file. How do you know if the .cdr file is ready to be archived? If mtime < 30 seconds old, the file may still be open and being written. The kernel syncs file data periodically, usually less than 1 minute intervals.

In any case you may be processing or trying to process incomplete or partially processed .cdr files. Note gzip does not rename the inputfile until after it completes, for example.

Also consider redirecting stderr in your cron entry:
Code:
2,4,6,8 * * * * /path/to/myscript.sh 2>>/path/to/errorlog.log

Then you can see what is going wrong. At least any errors.

virt-copy-in

virt-copy-in(1) 					      Virtualization Support						   virt-copy-in(1)

NAME

       virt-copy-in - Copy files and directories into a virtual machine disk image.

SYNOPSIS

	virt-copy-in -a disk.img file|dir [file|dir ...] /destination

	virt-copy-in -d domain file|dir [file|dir ...] /destination

WARNING

       Using "virt-copy-in" on live virtual machines can be dangerous, potentially causing disk corruption.  The virtual machine must be shut down
       before you use this command.

DESCRIPTION

       "virt-copy-in" copies files and directories from the local disk into a virtual machine disk image or named libvirt domain.

       You can give one of more filenames and directories on the command line.	Directories are copied in recursively.	The final parameter must
       be the destination directory in the disk image which must be an absolute path starting with a "/" character.

EXAMPLES

       Update "/etc/resolv.conf" in a guest:

	virt-copy-in -d MyGuest resolv.conf /etc

       Upload a home directory to a guest:

	virt-copy-in -d MyGuest skel /home

JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH

       This command is just a simple shell script wrapper around the guestfish(1) "copy-in" command.  For anything more complex than a trivial
       copy, you are probably better off using guestfish directly.

OPTIONS

       Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.

SEE ALSO

       guestfish(1), virt-cat(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), virt-tar-out(1), <http://libguestfs.org/>.
