Snapshots are used to create a point-in-time copy of a file system or file sets. |
|||
Snapshots can be used to quickly restore files or folders that were unintentionally deleted. Snapshots also provide a form of file versioning and the ability to revert to a previous version of a file, depending on the time interval between snapshots. |

Snapshots for LSDF storage projects are available in the sub directory ''.snapshots'' in the base directory of you OE (e.g. ''/lsdf/kit/scc/projects/.snapshots''). Snapshots for user home directories are available in the directory ''/lsdf/kit/.snapshots''. On the [[LSDF Online Storage:LSDF_Online_Storage:_Secure_Shelllogin machines|LSDF_Online_Storage:_Secure_Shelllogin machines]] these directories are mapped with two environment variables ''$PROJECTSNAPSHOTS'' and ''$SNAPSHOTS''. |
