Use the collocatebyfilespec option to specify whether the Tivoli® Storage Manager client uses only one server session to send objects generated from one file specification.
Setting the collocatebyfilespec option to yes attempts to eliminate interspersing of files from different file specifications, by limiting the client to one server session per file specification. Therefore, if you store the data to tape, files for each file specification are stored together on one tape (unless another tape is required for more capacity).
Considerations:
This option is valid for all UNIX and Linux clients. The server can also define this option.
This option is valid for all Windows clients. The server can also define this option.
Place this option in the client user-options file (dsm.opt).
Place this option in the client options file (dsm.opt).
Backup performance might increase as a result. If the files are backed up to tape, files are stored on multiple tapes. Generally, the files specified in the file specification are still contiguous.
This option is valid only on the initial command line. It is not valid in interactive mode.
