Backup and Restore Linux virtual machine using LUKS

Post by donteun »

Dear all,
Seeking the experience and expertise here,
Currently I have customer running Linux virtual machine on VMware ESXi
- All their Linux virtual machine are using LUKS disk encryption.
- Can I understand when we are using Veeam to backup is their any specifically settings or pre requisite Will this have an impact on the compression/Dedupe ratio??
- To do a full VM restoration or file level restoration, what will be correct process. As I understand (restoring file level) that it will be encrypted linking it back to a KMS server with a key.

There are no specific prerequisites to backup VMs with LUKS encrypted disks, however compression and deduplication do not work well with encrypted data.
If you want to restore the entire machine then the process is just the same as with regular disks. If you have KMS in place then the restored VM should be able to connect to it automatically after the restore is complete and thus decrypt the disk. File-level restore is not supported for encrypted devices.

Thank you
