backup(8)backup(8)NAMEbackup - Volume by volume backup of the Coda File System
SYNOPSISbackup [-p poll_period] [-t timeout] <dumplist> [dumpdir]
DESCRIPTIONbackup performs the clone and dump phases of the Coda backup mechanism.
dumplist is a file as described in dumplist(5). It also reads vicetab
which is described in vicetab(5) to know where to place dump files.
The backup program creates many lines of information as the phases
progress. It is a good idea to redirect standard output to a log file.
A sample of this log file backuplogs(5). After both phases are com‐
pleted, it prints out a list of volumes in several groupings, and some
histograms detailing size and speed of the dumpfiles transferred. The
first group are the volumes that were successfully backed up on all
servers in their VSG. The second group contains volumes that were suc‐
cessful on some, but not all of their VSGs. The third group contains
volumes that were complete failures. The last group contains volumes
that are in the VLDB or VRDB but not in the dumplist.
The second and third groups use an n-letter word to describe the last
successful operation that succeeded on each replica. The kth position
in the n-letter word corresponds to the kth replica in the VRDB entry
for this volume. One of four letters appears in each position: "L",
"C", "D", and "M". "L" means the replica was only locked, "C" means it
was cloned but not dumped, "D" means it was dumped (but not marked as
such on the server, see the discusion in the manual chapter on backup),
and "M" means all phases completed successfully.
backup supports the following command line options:
-p poll_period
Number of seconds to sleep between polls a servers that backup
thinks are down.
-t timeout
Timout value, in seconds, for RPC2 calls.
