Subject: [Hampshire] ext4 and dd disc cloning
My normal backup routine is to tar up my home directory files daily and
then every month or so do a full disc clone using DD

dd if=/dev/sda of=/dev/sdb bs=32M

This has worked for years but now fails to copy all files on Fedora 13.
Some directories like /sys have permissions ???? . I also tried
clonezilla using partclone which took 24 hours and then crashed. I think
this is the first ext4 backup I've done. The only other change is my
removable caddies which are now cheaper ones.

Any ideas?
