Fellow RSYNC users,
I recently decided to use 'rsync' to update a backup copy of my root
partition rather than doing a 'dump', 'restore', and a massage of the
/etc/fstab file. I've tried using a variation of the "backup to a spare
disk" example on the web page with bad results. I found that using the
"L" option visually appears to work much better. But I don't feel
comfortable with the error messages that come out when using the
verbose mode. I am running RSYNC version 2.4.6 on a BSDi 4.1 system
for this example.
I've appended examples in sort of reverse order, since the backup root
partition gets clobbered.
And, I may of answered my own question by producing the examples. The
destination partition is being mounted on the source partition, which
changes the /mnt directory. Shouldn't the "x" option take care of this?
I did try mounting /dev/sd1a on /usr/mnt and things did work as I intended.
This could be disasterous for others that may of assumed the same I did.
So if you have any suggestion or that this is a new or known bug, please let
me know.
