Disclaimer

The user community and its sponsoring organizations are very diverse with differing requirements for data retention. The Linac Coherent Light Source (LCLS) cannot guarantee indefinite data archival. Users of LCLS are responsible for meeting the data management requirements of their home institutions and funding agencies. Once data have been provided to the user group, the user group is responsible for managing the long-term retention of their data. The ownership of data generated at LCLS is governed by the User Agreement in place between the user group and the facility. Refer to your User Agreement for more details.

Data Retention Practices

LCLS is committed to providing its users with their data in a timely and convenient fashion. Experiment data and metadata collected at LCLS may be stored at and retrieved from the facility for a period of ten years. The data retention practices described in this page are on a best effort basis, they depend on availability of the actual resources and may change at any time if these resources become unavailable. Historically we have been able to deliver on these lifetimes (with the exception of scratch where, twice, we had to delete data newer than 4 months), but we cannot guarantee them: available resources depend on the actual usage rate and available funding, which we do not fully control. Notifications will be sent out when files are removed (scratch) or purged (xtc, hdf5) from disk.
