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?
We use this scenario with aix. Should work ok with windows. As long as
you are using HARDWARE raid, I think it is safe. I wouldn't trust
software raid to this task.
