Instructions

There are two types of Snapshots:
  • Read-Only (.ckpt) file snapshots
  • Read/Write (share) file system snapshots

For Read-Only (.ckpt) file snapshots:
It is possible to restore individual files from a snapshot without restoring the entire file system. This type of restoration is done through the Windows Previous Versions tab on recent versions of Windows, or by appending .ckpt to the share location on UNIX or older versions of Windows.

To view the Previous Versions of a file system in Windows, right-click the file system, select Properties, and then view the Previous Version tab. Administrators can then copy individual files that are associated with the snapshot back into the current production file system.

Read only


For Read/Write (share) file system snapshots:
In order to access a writable file snapshot, the user must create a share for this file system using the snapshot. This operation is accomplished through the same share creation wizard that is used to create regular shares, except Snapshot for File System is selected as the source during configuration. The administrator then provides a share name and path for the snapshot share similar to a regular file system share.
