Don't you create filesystems with mkfs/e2mkfs ?
You need to use dd to make a file to _hold_ the filesystem, but that's
just a chunk of data; it's not a filesystem until you use mkfs.
Not if the file system already exists and you just make a bit-for-bit
copy. I achieved that with a command along the lines of `dd
if=/dev/mapper/System-fc6 of=/mnt/external_hd/system_backup_file bs=4K`,
which then copied my filesystem as it exactly was. Then that image can
be mounted using a loop device (`mount -o loop
/mnt/external_hd/system_backup_file /mnt/backup_mount_point`)
Half of rsync is crashing; it forks. Run "strace -f", and then look at
the pid that _isn't_ the one printing the error message.
I eventually figured out that rsync has two parts to it (see BZ#248663),
but this would have been nice to know about before that. Thanks, and
I'll remember that for later! Even knowing that there was a segfault
would have helped: I spent hours trying to figure out if cron was
killing what it might have thought to be a "dead" process. I was only
lucky enough today to get a manual run of the script to fail on me.
