Backup of mounted encrypted folder = security risk?

[Afox]

Hello,

if I make a backup (Snapshot-mode) of a VM that currently has an encrypted folder mounted (ecryptfs). Would that be a security risk?

A snapshot on backup is made on the block level of the VMs disk. Ecryptfs is an encryption stack on top of a filesystem that encrypts data and/or directories, stored encrypted on the disk.

so what you want to say is that only the encrypted data gets backed up and there might only be a risk if a swap partition is used?

I don't know how SWAP is treated.
