some of us have audit requirements that demand that backup media be kept off-site. you need to choose your transportation system as wisely as you choose the other elements in your infrastructure. of course, we don't usually get to choose, we just have to adjust to what we have. at my last place, my boss had a motto for backups: we do backups to do restores, quickly! our production database backups (+1TB) were restored to a dev environment at least once a quarter. files were restored on demand, at least once per day (that's a user training problem). so, we knew that not only were our backups good, the process for doing large restores was also good. all of our daily backups were full, no incrementals. that's why the boss stressed quickly, no hunting through multiple tape logs. of course our tape vendor loved us and so did the off-site storage vendor! plus, ya gotta love tape libraries and robots! -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Kristian Erik Hermansen Sent: Monday, November 12, 2007 5:47 PM To: Tom Metro Cc: L-blu Subject: Re: untested backups On Nov 12, 2007 1:46 PM, Tom Metro <[hidden email]> wrote: > Ummm...an untested backup is almost as bad as having no backups. Yup! Insert wonderful example of backup to magnetic media on subway car :-) http://catless.ncl.ac.uk/Risks/15.21.html#subj6 While studying for the CISSP All-In-One exam book by Shon Harris, she gives an example of a company who stored all their backups, but used the subway to transport them to the facility when it came time for restoration (so they were even tested!), but the subway trains created a magnetic filed that wiped the data on the way to the facility. Lesson learned? Keep your data at the place of restoration and ensure it is tested :-) -- Kristian Erik Hermansen -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ Discuss mailing list [hidden email] http://lists.blu.org/mailman/listinfo/discuss -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. _______________________________________________ Discuss mailing list [hidden email] http://lists.blu.org/mailman/listinfo/discuss
