I didn't think they still existed but I'm willing to consider any backup strategy at the moment. On Saturday 18 January 2003 17:26, you wrote:
Have you ever heard of tape drives for doing backups?

OK. Then you have to decide the backup strategy:
1. The type of backup: - full backup only - incremental backup - differential backup - a mixture of the above
2. The frequency of the backup.
The decision depends on many factors, mainly: (1) the ratio between the amount of data you want to back up and the capacity of the
storage
space, (2) administrators' expertise, (3) the amount of money.
You can buy an expensive software where you simply select the backup strategy in a GUI environment or you can write a shell script which will do it without paying anything.
I don't recommend a complicated backup strategy (for instance a mixture of differential and incremental backups) if the administrators' knowledge is not good enough. A recipe how to
restore
the data should be in a folder but they may not understand it anyway.
The backup is not related to NIS or NFS.
I think I'll go for incremental daily backup via rsync, dump that to dvd once a month, clear out the backup directory and start again the next month with a new rsync'd copy. How does that sound. Or am I way off? Thanks for your patience, Steve.
