list is too long to compile. The members of this list and the exchange
of technical info is awesome! Thanks again!
The overwhelming suggestion is to use rdist with the -c option. But,
others responded with the following:
- include a -newer option with the cpio command.
- include -mtime +2 -ctime +2 -depth -print options with the find
command.
- use ufsdump and ufsrestore
- and several suggested to use rsync available through:
