Hi,

I have two 160Gb drives, one internal and one USB.  I've partitioned
them the same and created an identical filesystem on the USB drive for
backing up my internal drive.

I'm using the following rsync command to make the backup:
sudo /usr/bin/ionice -c 3 /usr/bin/rsync -aAx --exclude suspend_file
--delete --delete-excluded --partial
--human-readable / /media/root-backup

however, after running this command sporadically for a few days, the USB
partition is now full, whereas my root partition isn't!

sda is internal, and sdd is external.  sda7 is the one I'm interested
in:

$ sudo fdisk -l

I just deleted a bunch of /var/tmp and distfiles to free up some space,
and ran the rsync again.  Now it looks like this:

$ df -h
Filesystem            Size  Used Avail Use% Mounted on
rootfs                 92G   81G  6.1G  93% /
/dev/sdd7              92G   89G  4.6M 100% /media/root-backup

/dev/sda3              99M   39M   55M  42% /boot
/dev/sdd3              99M   39M   55M  42% /media/boot-backup

I'm doing the /root backup from cron, but the /boot backup manually when
I make changes.

I thought perhaps the ext3 options were different (ie. different amount
of "reserved" space) but that would make the "Avail" columns different,
and shouldn't make the "Used" columns different.

any thoughts as to why my USB partition is full?  thanks,

Most people have two reasons for doing anything -- a good reason, and
the real reason.
