we actually do full backups every night - we don't have that much to back up - ends up being about 110 GB a night, which gets done in 4-6 hours. Daily backups are kept onsite in a firesafe. Weekly backups are sent offsite for 8 weeks. We used to do monthly backups, but our current setup works just fine for us. Don't have to worry about incremental or differential backups. Not saying this is the best practice, but for our office, it would appear to be so. Obviously larger companies with more data to back up can't apply this sort of solution due to time and tape considerations.

We currently keep all tapes offsite except for the current day's set. We have an extremely simple rotation. M-W differential, overwritten weekly. Thurs and Fri are full, overwritten every five weeks. What do other orgs do? How do you balance data retention against liability? We have a policy that states data not on disk has a lifespan of five weeks...to avoid the Microsoft horror. Too short? I'm also wondering if more indepth backup rotations are useful in a smaller org like us...we typically back up about 150 gigs a week. Or are we still good with with diff/normal on a weekly basis? And does anyone else notice that the day after a backup fails, someone asks for a restore? How the heck to you get around that without having a parallel backup system doing the same backups? -----Original Message----- From: Hunter, Lori [mailto:[EMAIL PROTECTED]] Sent: Monday, October 01, 2001 11:57 AM To: MSWinNT Discussions Subject: RE: Off site backups Sounds like he read a blurb in a magazine. Does he really mean hire someone to TAKE backups or does he just want you to establish a tape rotation whereby most of your tapes are offsite at all times? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, October 01, 2001 1:34 PM To: MSWinNT Discussions Subject: Off site backups in lieu of sept 11th our CFO has asked me to research companies that do off site backups of client networks... I assume that a company comes in puts a node on your network and a T circuit and pulls backups off that way ove the internet? does anyone know what I am talking about?? if so does anyone know of or recommend a company that does this our backups are about 40 GB ------ You are subscribed as [EMAIL PROTECTED] Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe send a blank email to [EMAIL PROTECTED] ------ You are subscribed as [EMAIL PROTECTED] Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe send a blank email to [EMAIL PROTECTED] ------ You are subscribed as [EMAIL PROTECTED] Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe send a blank email to [EMAIL PROTECTED] ------ You are subscribed as [email protected] Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe send a blank email to [EMAIL PROTECTED]
