rsync has a lot of parameters, here you have a selection
-a, --archive
-a, --archive archive mode
same as -rlptgoD (no -H)
-r, --recursive recurse into directories -l, --links copy symlinks as symlinks -p, --perms preserve permissions -t, --times preserve times -g, --group preserve group -o, --owner preserve owner (super-user only) -D same as --devices --specials
commons
-v, --verbose increase verbosity
-u, --update skip files that are newer on the receiver
-z, --compress compress file data during the transfer
-e, --rsh=COMMAND specify the remote shell to use
-h, --human-readable output numbers in a human-readable format
--progress show progress during transfer
-f, --filter=RULE add a file-filtering RULE
incremental
-b, --backup destination files are renamed --backup-dir=DIR for incremental backups
limits
--max-size=SIZE --bwlimit=KBPS limit I/O bandwidth; KBytes per second

Backup using ssh
Commands to execute
At host to backup (as root)
useradd -g 0 -G daemon,dip,lpadmin,shadow,sasl rbackup passwd rbackup su - rbackup mkdir -p /home/rbackup/.ssh chmod 700 /home/rbackup/.ssh chown -R rbackup.root /home/rbackup
At backup server (as root)
ssh-keygen -t dsa -f diskarray.gacq.com-id_dsa scp diskarray.gacq.com-id_dsa.pub rbackup@diskarray.gacq.com:.ssh/authorized_keys
Test the key:
ssh -i diskarray.gacq.com-id_dsa.pub rbackup@diskarray.gacq.com

Diferences between ryncd and ssh
add/remove this
-e "ssh -l $USER -i $HOST-id_dsa"
and change the source
for rsyncd use:
$HOST::all $dir
for ssh use:
$HOST:/ $dir
duplicating systems with sync
rsync -v -r -p -o -g -D -t -S -l -H \ --exclude /mnt/ \ --exclude /proc/ \ --exclude /tmp/ \ --exclude /home/ / /mnt/fireball/
Boot from a CD-ROM and mount the target-disk. Fix fstab and lilo.conf. Create /mnt and /proc and set the right permissions (for this directories). Then run lilo and reboot. Next time you run rsync, add these option to the command-line:
--exclude /etc/fstab \ --exclude /etc/lilo.conf \ --delete
