Backup - was [nmglug] Raid Help

[Tim Emerick]

My thought process was as follows:

About 30 gigs of data broken out into 3 categories.

1. Static Data that is typically read-only (CD Images, HD Images, Network
Install Points) that rarely changes and I can regenerate quickly.

2a. Database that changes but I would need to backup the entire dataset to
restore the database.

2b. Variable Data that can change daily that users might accidentally delete.
 Accounting spreadsheets, etc.

pseudo-code:

rotate backups.
perform todays backup.
Delete any backups older than a defined number of days old.
Delete any backup data that meets criteria 2a and is older than 2 days.
delete any backup data that meest criteria 1 and is older than 1 day.

end-pseudo-code

I just use a simple cp to copy my shared directory to a large hard drive and
share it out as a hidden read-only samba share.  Backups are in directories
labeled 1-30 (or however many days I am going to retain).  Certain Admin type
users can retrieve Category 2b files from any number of days ago by browsing
to the hidden share/day number/data location.  ie. I want to retrieve a
spreadsheet from 3 days ago that I kept on the server in the /helpme folder. 
I would browse to //server/hidden$/3/helpme and retrieve the file.

It's rough and damn insecure but it works for me and my feeble users.

I've been looking into Bacula or some other samba based PC backup.

Oh well, other projects call.
