bpcp copies files between hosts utilizing NASA JPL's Interplanetary Overlay Network (ION) to provide a
delay tolerant network. File copies from local to remote, remote to local, or remote to remote are
permitted. bpcp depends on ION to do any authentication or encryption of file transfers. All covergence
layers over which bpcp runs MUST be reliable.
The options are permitted as follows:
-d Debug output. Repeat for increased verbosity.
-q Quiet. Do not output status messages.
-r Recursive.
-v Display version information.
-Lbundle_lifetime
Bundle lifetime in seconds. Default is 86400 seconds (1 day).
-CBP_custody
Acceptable values are ON/OFF,YES/NO,1/0. Default is ON.
-Sclass_of_service
Bundle Protocol Class of Service for this transfer. Available options are:
0 Bulk Priority
1 Standard Priority
2 Expedited Priority
Default is Standard Priority.
bpcp utilizes CFDP to preform the actual file transfers. This has several important implications. First,
ION's CFDP implementation requires that reliable convergence layers be used to transfer the data. Second,
file permissions are not transferred. Files will be made executable on copy. Third, symbolic links are
ignored for local to remote transfers and their target is copied for remote transfers. Fourth, all hosts
must be specified using ION's IPN naming scheme.
In order to preform remote to local transfers or remote to remote transfers, bpcpd must be running on the
remote hosts. However, bpcp should NOT be run simultaneously with bpcpd or cfdptest.
