When transferring BACKUP save sets to a different platform, please ensure that the transfer is done to assure that the contents of the file are not damaged. This requires a BINARY transfer. If the transfer is done using FTP in text mode, the contents of the save set will be damaged in a way that is generally not recoverable.
It is often a good idea to ZIP save sets before transfer (in particular, ZIP "-V" to preserve the OpenVMS file attributes). Once a file has been ZIP'ed, it is also possible to verify the integrity of the ZIP archive using the ZIP Test option on the other platform.
A roundtrip back to the OpenVMS system, and verification that the save set is usable, is also recommended.
