Hi, |
2 |
|
3 |
I have two 160Gb drives, one internal and one USB. I've partitioned |
4 |
them the same and created an identical filesystem on the USB drive for |
5 |
backing up my internal drive. |
6 |
|
7 |
I'm using the following rsync command to make the backup: |
8 |
sudo /usr/bin/ionice -c 3 /usr/bin/rsync -aAx --exclude suspend_file |
9 |
--delete --delete-excluded --partial |
10 |
--human-readable / /media/root-backup |
11 |
|
12 |
however, after running this command sporadically for a few days, the USB |
13 |
partition is now full, whereas my root partition isn't! |
14 |
|
15 |
sda is internal, and sdd is external. sda7 is the one I'm interested |
16 |
in: |

$ sudo fdisk -l |

I just deleted a bunch of /var/tmp and distfiles to free up some space, |
53 |
and ran the rsync again. Now it looks like this: |
54 |
|
55 |
$ df -h |
56 |
Filesystem Size Used Avail Use% Mounted on |
57 |
rootfs 92G 81G 6.1G 93% / |
58 |
/dev/sdd7 92G 89G 4.6M 100% /media/root-backup |
59 |
|
60 |
/dev/sda3 99M 39M 55M 42% /boot |
61 |
/dev/sdd3 99M 39M 55M 42% /media/boot-backup |
62 |
|
63 |
I'm doing the /root backup from cron, but the /boot backup manually when |
64 |
I make changes. |
65 |
|
66 |
I thought perhaps the ext3 options were different (ie. different amount |
67 |
of "reserved" space) but that would make the "Avail" columns different, |
68 |
and shouldn't make the "Used" columns different. |
69 |
|
70 |
any thoughts as to why my USB partition is full? thanks, |

Most people have two reasons for doing anything -- a good reason, and |
75 |
the real reason. |
