If the backup is just one huge file (mine would be 2-3 GB), what if you
just want to restore one file, or even just LOOK at one file?

cp -r myprofile/ /myprofilesave/ is pretty easy too :-)

I would prefer rsync. In fact, i regularly save not only my profile or
my home but my whole Gentoo. *g*

rsync -av --delete -F --exclude-from /home/hafi/.rsy-ex / /rsy_64

hafi@i5_64 ~ $ df -h /rsy_64
Filesystem Size Used Avail Use% Mounted on
/dev/sdb11 290G 112G 163G 41% /rsy_64

That does not take much time. Since the last backup there were several
updates of Gentoo, including Libreoffice with source. Also, because i
compile daily my SeaMonkeys from latest source, there are a lot of
changes. Several GB.

hafi@i5_64 ~ $ du -hs hg-moz
2,2G hg-moz
hafi@i5_64 ~ $ du -hs moz-work
3,3G moz-work

I have just finished a backup. The elapsed time:

hafi@i5_64 ~ $ time sudo rsy
[...]
real 5m45.632s
user 0m33.400s
sys 0m45.272s

I have one usb drive that i use for backup

# cd /..../media/gerardjan
# rm -rf */home
# find /home | cpio -dumpv *

i try to do that every day, works like a champ...

sincerely

Have your consultant write an rsync script and run it from cron.

He's already written some very nice full backup routines that yield
bootable partitions. HD space is cheap.
