- JJccooppyy is volume-to-volume utility for the Jaquith system.
-
-
- Jcopy copies one Jaquith volume to another, in its entirety.
- The assumption is that the source tape is growing old and
- that the data is being rolled forward to a new tape. There-
- fore, Jcopy attempts to keep Jaquith's view of the world
- up-to-date by editing various configuration files. The user
- is prompted about these changes at the appropriate time.
-
-
- Omitting the --ddeessttvvooll option entirely will cause jcopy to
- obtain a volume from Jaquith's free volume list.
-
-
- Jcopy negotiates with jmgr to mount the volumes. This means
- that jcopy can run while the system is publicly available.

-
- Jcopy does not connect to the public port managed by the
- Jaquith process to discourage its use as a client program.
- This is because Jcopy makes no attempt to obtain the two
- devices atomically. Therefore it's possible for two jcopy
- processes to deadlock, each holding 1 device and unable to
- get the other.
