Interesting:

I am currently using rsync to copy about 30G's of data from one server to another (raid'd) server. Both run debian sarge. The command I used:

rsync -avz -e ssh user@addy/dir/ /dir/

anyway, the remote server being copied from has tons of files, with most of them having a group of 'hmnetw' to specify the home network group for multiple users. But the group 'hmnetw' did not exist on the new server. The files look okay, and they have the correct dates, etc. But anything that formerly had 'hmnetw' now has the group '104'.

I am wondering the implications of this.
Any insight apprec.
Thanks,

Bad answer Ignore.

That's an easy one. When you copied the files over, it kept the group number that hmnetw. Go ahead and great a group called 'bob' or whatever, make sure it has number 104 (on the destination server of course) and you will see why. Because of this, I like to make sure groups are synched (not rsynched though )

Thanks for that. You're right, and i've researched and now know why. This is very helpful to me.

Cheers Sip.
