LTS provides NFS and CIFS Storage as well, but both back ends are autonomous devices, i.e. one might use either NFS or CIFS to store data (not concurrently).
The LTS archive system is intended as a final storage for thesis, projects and other invariant data. It is not a backup system.
Although the LTS Archive is hosted by ID access is granted by ISG only! Due to its design as a long term storage access is provided to nonpersonal accounts only. In practice, each institute or group is entitled to request a special LTS account. The account's credentials are hold by the person in charge, e.g. Professor, group leader or local IT-Admin. In some exceptional cases access is also given to a project account.

The usage of LTS causes some strict requirements and limitations:
- Access is either NFS or CIFS (no concurrent access)
- Data must be packed in an archive (e.g. TAR, ZIP etc.)
- Data must be collected and prepared in a pre-processing task (best on local scratch disk)
File size < 2TB but at least > 5GB (best between 10GB and 200 GB)
- No data appending after storing on LTS (data are invariant)
- Non security mechanism against data deletion by mistake
- Full data deletion is not possible (on request only)
- Meta information can be stored within file name only
- File/dir name length is limited to 255 chars
- Total path length is limited to 3900 chars
- For reading copy data from LTS to local disk first
