Be careful with USB keys. In my experience, you'll run in to integer
size problems with the database format. For example, I cannot access
a monotone database (SQLite) on my amd64 Linux port that was created
on a i386 Linux port. To synchronize, I needed to dump/read or make a
network connection between the two. As a practice, I now dump and
compress monotone DB's to my USB key.
--------------->8------------------
#!/bin/sh
# NOT TESTED
# Dump databases
MTDIR=$HOME/.monotone
DATABASES=personal.db work.db
for i in $DATABASES ; do
monotone -d $MTDIR/$i dump | bzip2 > ${i%db}sql.bz2
done
--------------->8------------------
#!/bin/sh
# NOT TESTED
# Dump databases
MTDIR=$HOME/.monotone
# Create the staging directory (assign default if not provided)
[ ! -d ${STAGEDIR:=/tmp/monotone-sync} ] && mkdir -p $STAGEDIR || exit 1
# Load them to new databases
for i in *.sql.bz2; do
bzip2 -cd $i | monotone -d $STAGEDIR/${i%sql.bz2}.db load
done
# Now synchronize them with local ones
for i in $STAGEDIR/*.db ; do
if [ -f $MTDIR/$i ] ; then
monotone -d $i serve --bind localhost serve \* &
monotone -d $MTDIR/$i pull localhost \*
kill %monotone
else
cp $i $MTDIR
fi
# Remove the DB
rm $i
done
--------------->8------------------
Creating the db's in a memory resident filesystem would help speed
things up a bit. i.e. tmpfs
I hadn't thought of this before, but it might be useful to store DB's
in arch-dependent directories or perhaps name them accordingly.
