dvbackup for Debian
-------------------
* dvbackup depends on rsbep, a useful error correction
algorithm. On other architectures that i386 you have to use rsbepC, the
somewhat slower version implemented in pure C, instead of rsbep.
* Your system and the tool you use to generate the backup stream (tar for
example) should be able to provide 3.6 MB/sec _sustained_ datarate.
Otherwise you will get underruns and can't use the full capacity of
the tape.
* Ideas of backup scripts are in /usr/share/doc/dvbackup/examples
* A useful commandline for a backup could be (you have to start and stop
recording yourself, these only do the streaming):
# tar cpsvv /home /etc /usr /bin /sbin /root /var | \
rsbep | \
dvbackup --verbose --prefix 120 --set-backup-title "full 2004-02-19" | \
dvconnect --send --underrun-data /usr/share/dvbackup/underrun-pal.dv \
--buffers 512 --device /dev/video1394/0 -- -
For verification:
# dvconnect --device /dev/video1394/0 | \
dvbackup --decode --verbose | \
rsbep -d -v | \
tar Oxvv > /dev/null
And for rescue (never tested, as no one ever tests "worst case" ;-):
# dvconnect --device /dev/video1394/0 | \
dvbackup --decode --verbose | \
rsbep -d -v | \
tar xvv
