CAN-02: Managed data transfer
|Effort and Costs:||
Quality attribute CAN-02.m (Preserving file metadata) describes a need to ensure that the file-system metadata on the destination system matches the metadata on the source when a transfer completes. (Metadata includes file attributes, such as date and time stamps or permission settings.) All attributes are currently supported except for the “last accessed” timestamp. Most of the destination systems used by XSEDE users do not provide mechanisms for setting this attribute, so XSEDE does not support synchronizing the “last accessed” timestamp.
