The fsretrieve command usually retrieves the primary copy of the file requested. If the primary copy is inaccessible or corrupted, the command defaults to the secondary copy. Completion status returns when the files are successfully copied onto disk. The fsfileinfo command can be used to determine if a file is on tape, disk, or both.

The file in the migration directory is associated with its media copy. When the file on disk is modified, but has not been stored to media again, the version on the media is invalidated and cannot be retrieved from the media with the fsretrieve command.

The file version that resides on disk is always assumed to be the current version. If the file is removed from disk using the UNIX rm command, the file is logically deleted from the media.

Note

When the UNIX rm command is used to remove a file, only the Primary copy of the file can be recovered with the fsundelete command. The rm command removes the Secondary copy of the file from the database.

The file data still resides on media, but it is no longer tracked and can only be retrieved from the trashcan using the fsundelete command. This retrieval is valid until fsclean is used to purge the trashcan.
