Would they be re-usable. i.e. Could I copy the data files, and could
they be used again if copied over the other files? I am thinking about
a backup strategy for the LDAP data.
We do too. The think is that currently, we are relying on JDBM, and if
the server crash severely well, you may lost some data. This is
certainly not something we can accept. Now, this is the bad. About the
good : a LDAP server is known to be read most of the time, and written a
few. If we backup the JDBM files, hourly, we will be able to restart the
server and only lost a few modification. The ChangeLog system will be
extended in the next few days to write a journal (a LDIF file) in order
to be able to restore the server state. As we have a unique revision
number associated with each modification, a bit like subversion, we
should be able to apply this journal starting at some specific point in
the past we know to be good.
Copying files hourly should be ok, this should be less of an issue, as
we would have a replica server on the other side of the world.
Now that sounds good. Especially if it can be emailed to an ML after
each change.
Those two features are for us the _most_ important things we want to
work on, and we want to start working on it right now, in order to get a
production ready server.
As our American friends might say, "Shweeeeet"
Cheers,
Tony
