What exactly does Vagrant snapshot save?

Question

I use Vagrant on VirtualBox. Yesterday, I saved a snapshot of my project by running:

$ vagrant snapshot save 'my-project-date-time'

Today, I've made some changes to files and folders in my project that I want to revert. When I run:

$ vagrant snapshot restore 'my-project-date-time'

... the restoring process is completed successfully, yet the changed files and folders in my project remain the same and do not revert to the sate they were when the snapshot was taken yesterday.

So what exactly does the Vagrant snapshot save?

Unroot

It depends on the provider. AWS: snapshot = ebs snapshot ovirt: native libvirt disk snapshot etc – Poleaxe

sorry, but what??? – Unroot

Vagrant snapshots just call the provider "snapshots" method. So Vagrant snapshot on virtualbox just calls virtualbox snapshot.

is there a way I can include project folder into a snapshot? – Unroot

If the provider doesn't support it, then no. And i'm 99% sure you can't do that with the functionality. you could sync the folder into VBOX and use cp to put it on the FS then snapshot however – Poleaxe
