RE: EMC Timefinder

Wow,

This reply is little bit different. I thought BCV and RMAN go hand in hand. I never thought BCV or RMAN. I do understand the power of RMAN, But considering the time it takes to do the BAckups/REstores as supposed to BCV, Its defeated. BAck in my previous environment, I used SQL B/T, Backup the volumes, Do a Split and REstore those volumes to the failover machine. Since SQL B/T handles most of the issues, I am fine with that. Here Rman throws me out saying that DBID is already registered in another source and so cannot backup. The real question is 1. What steps to follow? 2. What Order to follow?

I am very new to RMAN and so these procedures confuse me..

Thanx

Srikanth

Srikanth,
 We used to have BCVs/Symmetrix on somany production databases. But most of the
databases are moving from BCVs to RMAN. Infact there are very few BCVs left.

 With RMAN we can do the hot backups and also do not need another machine to synch up the BCVs. Also instead of using Symmetrix storage for space, Tape is
used for backups using EDM software. RMAN allows us to duplicate the database
onto another machine (that way production db can copied to test db with a different file structure and DB name)

 So do some research on what you want, BCV or RMAN for your backup needs. Both
have pros and cons...
