RDUMP(8C) — UNIX Programmer’s Manual
NAME
rdump − file system dump across the network
SYNOPSIS
/etc/rdump [ key [ argument ... ] filesystem ]
DESCRIPTION
Rdump copies to magnetic tape all files changed after a certain date in the filesystem. The command is identical in operation to dump(8) except the f key should be specified and the file supplied should be of the form machine:device.
Rdump creates a remote server, /etc/rmt, on the client machine to access the tape device.
SEE ALSO
DIAGNOSTICS
Same as dump(8) with a few extra related to the network.
BUGS
High density tapes (i.e. 6250 BPI) are by default written with 32∗1024 byte records. Older versions (including 4.2bsd) of /etc/rmt, only allow 10∗1024 read or write operations, thus causing rdump to fail. Use the "b 10" option to rdump(8) to get around this problem.
