Ah, I see.  I do weekly backups on this home system.  There's not a vast 
amount of data to handle, so weekly is OK here.  My backup script does 
Grandfather-Father-Son rsyncs to three different drives, so there are 
always two 'historic' copies.

I can see that in an office, with a lot of data, having hourly, daily, 
weekly, etc., snapshots is much more important.

Thanks for the clarification.  (I can relax.  Phew!)
