The subfilecachesize option specifies the client cache size for adaptive subfile backup.
If the cache size is too small, base files for some files will not be cached and subfile processing will not apply for them. However, setting the value too large can take up more disk space than can be spared. The files maintained in the cache should closely reflect the files used on a regular basis.
This option is valid for all Windows clients. The server can also define this option.
Place this option in the client options file (dsm.opt). You can set this option on the Backup tab of the Preferences editor.
This option is valid only on the initial command line. It is not valid in interactive mode.
