Before you restore VM guest OS files from storage snapshots, check the following prerequisites:
- You must add the storage system to the backup infrastructure.
- You must check limitations for Veeam Explorer for Storage Snapshots. For more information, see Veeam Explorer for Storage Snapshots.
- If you plan to restore VM guest OS files to their original location, make sure that VMware Tools must be installed on the target VM.
- Veeam Backup & Replication restores ACL for recovered VM guest OS files. To let Veeam Backup & Replication detect the target Linux system architecture and kernel version, make sure that the following utilities are installed on the VM guest OS: arch and uname.
- Veeam Backup & Replication must have access to the guest OS of the target VM to be able to deploy a coordination process. The coordination process performs a number of administrative actions on the target VM guest OS, for example, collects information about mount points.
- [For Linux/Unix-based target VM] Veeam Backup & Replication uses the SSH protocol to communicate with the target Linux/Unix VM and requires the SCP utility on the target VM. Make sure that the SSH daemon is properly configured and SCP utility is available on the target VM.
- [For storage systems working over Fibre Channel] To let Veeam Backup & Replication present snapshots of LUNs to an ESX(i) host, you must register the ESX(i) host with a WWN ID on the storage system.
- [For NetApp storage systems] Depending on the storage type, you may need to install additional licenses on the storage system. For more information, see Required Licenses for NetApp.
