Backup Options
Lock-Copy-Unlock
- Methodology recommended by Rational
- Results in a perfect backup
- Can be performed faster if disk-to-disk transfers are possible
- In process VOB write operations will hang until the VOB is unlocked
- This is the easiest and least hardware expensive method
MultiSite
- Backups with no VOB locks are possible
- Triggers, DO’s and non-VOB stored data are not copied
- MultiSite administration required
- Restorations tend to be non-trivial, require expertise
- Purchasing MultiSite for this purpose is expensive
- Requires two CPU’s with equivalent disk space
