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 target VM, mind the following:
- Veeam Backup & Replication uses the SSH protocol to communicate with the target Linux 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.
- SELinux must be disabled on the target VM.
- A range of ports that are used for data transfer must be open on the target VM.
For more information on configuring connection settings for Linux servers, see the SSH Connection step of the New Linux Server wizard.
- [For storage systems working over Fibre Channel] To let Veeam Backup & Replication present snapshots of LUNs to an ESXi host, you must register the ESXi 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.
