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 Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000080 Device Boot Start End Blocks Id System /dev/sda1 1 11 88326 6 FAT16 /dev/sda2 * 12 4875 39070080 b W95 FAT32 /dev/sda3 4876 4888 104422+ 83 Linux /dev/sda4 4889 19457 117025492+ 5 Extended /dev/sda5 4889 7321 19543041 83 Linux /dev/sda6 7322 7384 506016 83 Linux /dev/sda7 7385 19457 96976341 83 Linux Disk /dev/sdd: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x5d5d0036 Device Boot Start End Blocks Id System /dev/sdd1 1 11 88326 6 FAT16 /dev/sdd2 12 4875 39070080 b W95 FAT32 /dev/sdd3 4876 4888 104422+ 83 Linux /dev/sdd4 4889 19457 117025492+ 5 Extended /dev/sdd5 4889 7321 19543041 83 Linux /dev/sdd6 7322 7384 506016 83 Linux /dev/sdd7 7385 19457 96976341 83 Linux 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, -- Iain Buchanan <iaindb at netspace dot net dot au> Most people have two reasons for doing anything -- a good reason, and the real reason.
