We have performance using Concurrent Copy used by CA Disk BACKUPCC. How can we increase them?
Due to a huge number of ZFS files never backup as they are always open, the solution is to use CA Disk BACKUPCC which calls Concurrent Copy to perform this.
To get better performance in using Concurrent Copy with CA Disk you need to:
- Check if you may separate the number of ZFS to backup in several jobs
- Run them in parallel or sequentially depending on your CPU power
- Use a system where you will have more CPU and memory
- Do it at a low activity period
All of these depends on the size of data to backup, but using such powerful system can reduce a lot the elapse time consumed.
Another to verify is that IBM PTF OA66423 is applied.
As usual if you have any additional question, please contact our CA Disk Support team.
