Some background;
I'm using a 160GB USB harddisk to write dumps to. This disk is encrypted
with GEOM_ELI;
umass0: Prolific Technology Inc. Mass Storage Device, rev 2.00/1.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <WDC WD25 00JB-00REA0 20.0> Fixed Direct Access SCSI-0 device
da0: 40.000MB/s transfers
da0: 238475MB (488397168 512 byte sectors: 255H 63S/T 30401C)
GEOM_ELI: Device da0.eli created.
GEOM_ELI: Encryption: AES-CBC 256
GEOM_ELI: Crypto: software
Since I've converted my largest partition (/home) to GEOM_ELI as well,
I'm having trouble making backups.
slackbox:~$ df -h

Backing up non-encrypted partitions like /, /usr and /var works
fine. But when I get to /home, the following happens;
