Hi All,
Our client is still using iData agent to Backup VM’s. To convinse then for moving from iData agent Backups to VSA backup pleaseprovide pros and cons of VSA Bakcups.
Page 1 / 1
To name a few:
- Less impact op the performance of the applications running on the VM because the backup is offloaded to a acces node
- Improved RTO in case of DR
- It's simple to configure from a end user perspective
- Only agents required when you need to perform specific application level backups
In addition to Onno's reply:
Please note, functions might not be available depending on the hypervisor you are using.
Pro:
- Additional options can be introduced to the customer, such as VM replication and failover
Replication of Virtual Machines (commvault.com) - VM migration options are available thru Commvault
Cross-Hypervisor Restores (VM Conversion) (commvault.com)
Con:
- When using ‘slow’ storage there can be an impact on VM performance when disk consolidation is performed
- Legacy applications / cluster solutions can experience timeout issues when the when disk consolidation is performed
- Non default Linux kernels can have issues regarding quiescing
- Shared disks cannot be backed up
