In my former life, this was more of a matter of OS not so much database. If both the live and the backup server are Windows based, there are a few different products available in the market.
I expect that there are a few Linux products for this. If it is AIX, Solaris, HP-Ux, etc, there are probably fewer choices. --Bill -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Jeff Powell Sent: Monday, July 26, 2010 10:34 AM To: U2 Users List Subject: Re: [U2] 24 X 7 MV systems Baker, My company has a 2 hour window backup to a standby server using rsync based sbom backup. At 10:00, 12:15, 3:00 and 6:00 we pause, split, resume and backup from the detached mirror. Recovery is far from automated but it fits our business needs.
