I am installing Linux Fedora Core 2 over a an older RedHat version, 7.1. The

the system.
I've tried TAR and SMB only to create ever increasing volumes. The problem I
think is that my attempts are chasing the links instead of simply backing up
the links. I simply want to create a backup that I can copy back, untar or
the like, if I must re-create the system. All my software is a CVS archive,
however much of the meddling I've done to Linux is in the libs, file
structures, links, .conf files and the like.
Any direction will be greatly appreciated.
How about just using rsync for backup?
rsync -a source_dir destination_location
And if the destination is on a remote machine:
rsync -az -e ssh source_dir user@remotemachine:destination_location
To get you started with rsync, here is a sample config:
On the backup server:
/etc/rsync.conf
motd file = /etc/rsyncd.motd
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
[rsync]
path = /home/rsync
comment = Rsync Backup Server
uid = nobody
gid = nobody
read only = no
list = yes
secrets file = /etc/rsyncd.scrt
Start the rsync server with:
# rsync --daemon
On the machine with the data to be backuped:
#!/bin/sh
# backup server
BSERVER=192.168.200.17
# backup options
# see: # man rsync
OPTS="--force --ignore-errors --delete -a"
# directory to backup
BDIR=/home/user
# do the backup
rsync $OPTS $BDIR $BSERVER::rsync/
So everything in /home/user gets backuped to the server in /home/rsync
For further details see 'man rsync'
