Re: BackUp on-line

[Jim C <jcllings@tsunamicomm.net>]

Pseudo code for backup script:

1. Replace the ACLs with some that specify that clients may not add or 
change data but may read.
2. Restart the server to have the new ACLS take effect.
3. Do your backup.
4. Put the old ACLs back.
5. Restart the server to have the client write privledges restored..
