What is an Ideal Backup Strategy

Well depending on how much data you want to backup. A meduim size company can sometimes have TB's of data. Also is all the data on 1 server? Several servers? etc
Personally I like using tapes still if I am to do a backup. CD's have been known to fail when you need to get data off them, yes even if they are stored in the right environment. DVD's yeah they hold more data though there is no long-term track record of using them for storing data on. Tapes have been used for years.
Or depending on the type of data you want to backup, how much etc you might just want to setup a 2nd HDD and make a image of the main HDD like say once a week.
It all depending on the servers, data size, what your budget is also helps, and so on. I would suggest getting a Unix Administration book on backup and recovry and reading through it and come up with the best plan for your business. Some people like to make there own configuration for the backups instead of using someone else's.
Cheers

bdb.db0
BDB.DB0(5) AFS File Reference BDB.DB0(5) NAME
bdb.DB0, bdb.DBSYS1 - Contain the Backup Database and associated log DESCRIPTION
The bdb.DB0 file contains the Backup Database, which records configuration information used by the AFS Backup System along with cross- indexed records of the tapes created and volumes dumped using the Backup System commands. The bdb.DBSYS1 file is a log file in which the Backup Server (buserver process) logs each database operation before performing it. When an operation is interrupted, the Backup Server replays the log to complete the operation. Both files are in binary format and reside in the /var/lib/openafs/db directory on each database server machine that runs the Backup Server. When the Backup Server starts or restarts on a given machine, it establishes a connection with its peers and verifies that its copy of the bdb.DB0 file matches the copy on the other database server machines. If not, the Backup Servers use AFS's distributed database technology, Ubik, to distribute to all of the machines the copy of the database with the highest version number. Use the commands in the backup suite to administer the Backup Database. It is advisable to create a backup copy of the bdb.DB0 file on tape on a regular basis, using the UNIX tar command or another local disk backup utility. SEE ALSO
