Shadow Copy (also known as Volume Snapshot Service, Volume Shadow Copy Service or VSS) is a technology included in Microsoft Windows that allows taking manual or automatic backup copies or snapshots of computer files or volumes, even when they are in use. It is implemented as a Windows service called the Volume Shadow Copy service. A software VSS provider service is also included as part of Windows to be used by Windows applications. Shadow Copy technology requires the file system to be NTFS in order to create and store shadow copies. Shadow Copies can be created on local and external (removable or network) volumes by any Windows component that uses this technology, such as when creating a scheduled Windows Backup or automatic System Restore point.

    Solved Browse snapshots of encrypted shares?

    Most of the shares on my Synology aren't encrypted, but I do have a couple that are encrypted. I've noticed that I can browse any of the snapshots of the 'regular' shares when I want to find & restore a few files or folders. But with the encrypted shares it seems like I can't select a snapshot...

    Where does DSM store configuration credentials for Snapshot Replication?

    I'm using snapshot replication to backup my primary NAS to a secondary NAS. To do this, you have to set credentials on the primary NAS for an admin user on the target NAS. I'd prefer to use a service account that only has the required permissions, but according to Syno support this isn't...
