Mark, Have you had to use those backups? What sort of experience if any have you had trying to read the data off them? Thanks. Boris. I have been with the company 10 years and never seen or heard of them being a problem but then again the IT guy is very secretive about what he does.

Sorry, that should have read "... a very large TAPE changer ...". With our current 2TB doing a price comparision it was a no-brainer to go with disk based backups. But once you need multiple disks for a single backup I suspect other factors may come into play. So I'd be interested to learn your conclusions. > Out of curiosity what do you currently backup (your 20TB) to? > -- > Brian Cryer > http://www.cryer.co.uk/brian > |
