I've been investigating using rsync to backup my Astlinux box on a regular
schedule from a remote client. I have it working from my Apple Mac with no
changes to the Astlinux box. The command I use to accomplish this is...
rsync -avz -e "ssh -p<my-port#>"
<user>@<my-Astlinux-ip-addr>:/oldroot/mnt/asturw
/Users/david/Documents/Astlinux
working nicely, except that I want to automate it which won't work as long
as it asks for my ssh password.
BTW... user could be "root" which is what I am using for test purposes. And
the only reason I need -p<my-port#> is because I have moved ssh away from
port 22.
As for password, I found through the wonders of google that I can create an
ssh security key, and then send the public key to the astlinux box. I did
this... placed the public key in to /root/.ssh/authorized_keys and then
modified the above command to...
rsync -avz -e "ssh -p<my-port#> -i <my-private-key-file>"
<user>@<my-Astlinux-ip-addr>:/oldroot/mnt/asturw
/Users/david/Documents/Astlinux
And now it runs rsync without prompting for password. Nice.
OK, now for the question... I can't see where this authorized_keys file is
getting saved onto my Unionfs partition. Therefore I am wondering whether it
will survive a reboot (I've not tried it, because I'm testing on the box
that I am connected to the internet through).
Can you tell me if root's home directory is saved to Unionfs. If not, then
if I create another user (how would I do that?) will its home directory get
saved to Unionfs. And/or if that won't work is there a config file
somewhere that I can tell ssh to look somewhere other than /<user>/.ssh/ for
the keys?
Thanks
David
