umm, not quite so simple for Amanda. Amanda uses native backup tools. So, on Solaris with ufsdump, /etc/dumpdates is managed by ufsdump, and Amanda references that. On a client using GNUtar, Amanda points to /etc/amandates. However, with 2.6, Amanda changed that to, I believe, /var/amanda/amandates or /var/lib/amanda/amandates. See: http://wiki.zmanda.com/index.php/Can_not_read-write_etc-amandates:_Permission_denied http://wiki.zmanda.com/index.php/Amandates Note that, while it says "on the client only", the server can also be a client. If the server is backing itself up, then this will appear on that machine as well.
