Here is some output from my daily backup script: Tarring various stuff ... tar: dev/.static/dev/gpmctl: socket ignored tar: dev/gpmctl: socket ignored tar: dev/log: socket ignored tar: root/.elinks/socket0: socket ignored Tarring home ... Tarring var various ... tar: var/lib/zope2.7/instance/mvr/var/zopectlsock: socket ignored tar: var/run/dbus/system_bus_socket: socket ignored tar: var/run/mysqld/mysqld.sock: socket ignored As far is I know this is no problem. I couldn't tell you exactly what a socket is, but I think it provides some sort of way for client programs to connect to a server program (daemon). It can be seen here that it is created at the time a program is started: $ ls -l /var/run/mysqld/mysqld.* -rw-rw---- 1 mysql mysql 6 2005-06-09 12:17 /var/run/mysqld/mysqld.pid srwxrwxrwx 1 mysql mysql 0 2005-06-09 12:17 /var/run/mysqld/mysqld.sock You don't need this socket file in a backup. It should disappear when you stop the service it belongs to. Let's check: $ sudo /etc/init.d/mysql stop Password: Stopping MySQL database server: mysqld. $ ls -l /var/run/mysqld/mysqld.* ls: /var/run/mysqld/mysqld.*: No such file or directory > There were two in the /dev directory - flew past too quickly tho, I > don't know what they are - and a couple in the /var/spool/postfix eg: > > prw--w--w- 1 postfix postdrop 0 2005-07-18 01:27 pickup > > I got the error both with cp -av and tar cfv > > Will these sockets be recreated once I run postfix after restoring the > system, or is there another way to safely backup and restore them?
