All -
We are attempting to enact IBM's double mirrored striped set backup alternative. This is where your server has a RAID array of 0+1 and then a second Raid 1 that is mirrored to the first mirror. The process as IBM describes it is: 1. Quiesce the database (pause all writes, data can still be read, no loss of data) 2. Split off the second set of mirrored drives 3. Restart the database 4. Backup system using split off hard-drives 5. Rejoin the mirrors Has anyone used this scenario in a windows environment? Wondering what types of RAID systems people are using? - (3) Arrays all of which are Raid 0 and in the OS you mirror those RAID 0's - A Raid 0+1 Array and another Raid 0+1 and then in the OS mirror the 2 Arrays - (3) Arrays Raid 0+1 and in the OS you mirror the 3 arrays Were there any drawbacks to this scenario? Any scenarios that works better? 2 final things to keep in mind, we are not in a SAN and we are not doing Transaction Logging. Thanks.
