Hi Shamus,
At least with Asterisk 11 which uses sqlite3, the writes seem to go directly to
disk, for example...
shell pbx # echo '.dump' | sqlite3 --batch /mnt/kd/astdb.sqlite3 | grep
'/foo/bar'
(nothing)
asterisk pbx*CLI> database put foo bar 0
shell pbx # echo '.dump' | sqlite3 --batch /mnt/kd/astdb.sqlite3 | grep
'/foo/bar'
INSERT INTO "astdb" VALUES('/foo/bar','0');
asterisk pbx*CLI> database del foo bar
shell pbx # echo '.dump' | sqlite3 --batch /mnt/kd/astdb.sqlite3 | grep
'/foo/bar'
(nothing)
So, from this simple test the /mnt/kd/astdb.sqlite3 file seems to be kept
current in real time. I suspect occasional rsync's should work though you may
want to make a temp copy of /mnt/kd/astdb.sqlite3 and rsync that just in case
the /mnt/kd/astdb.sqlite3 got written to while the rsync was still active.
