Hi,

v8.4.20

This is what the current backup script uses:

/usr/bin/psql -U postgres -c "SELECT pg_start_backup('Incrementalbackup',true);"
cp -r /var/lib/pgsql/data/* $dumpdir/data/
/usr/bin/psql -U postgres template1 -c "SELECT pg_stop_backup();"


That's fine, as long as you have a wal archive.  Although I don't know what is "Incremental" about it.

From reading the docs, that field is just a label with no intrinsic meaning.

Its purpose is to communicate with you.  If the person who implemented my backup solution is attempting to communicate with me, and I have no idea what that communication means, then that makes me quite nervous.

Cheers,

Jeff
