[BackupPC-users] which one better ssh+rsync or rsyncd ?

[J. B. <bak...@gm...>]

Dear list,

Greetings to all of you. I have come to know about backuppc recently during my search
for a net based backup solution which requires bare minimal settings at user end and
supports various client OS. backuppc surely meet my requirement.

I am confused about the server-client authentication. The ssh+rsync is very attractive,
but I like to restrict the passwordless key so that only and only the commands required
to complete the backup operation should be performed. Within the from field in the key
I can hard code the server IP, but how can I restrict the commands ?

Alternatively the rsyncd is also my consideration and I wonder how superior it is
over ssh+rsync. Please give some clue on the above said topics so that I can follow
the right direction.

Thanks
