We've been reviewing our policies and procedures in backing up data for
disaster recovery.
Currently, we backup the postgresql database in two ways:
-- pg_dump of the dspace database
-- snapshot of the dspace database
Our snapshot is a snapshot of the live, running database of postgres. I know
this isn't the right
way (that's why a pg_dump is performed every night).
Is anyone automatically shutting down their postgres, taking a backup/snapshot,
and
then bringing it back online? If so, answer the following:
1. Are you shutting down tomcat so dspace is not available? How
long is it not available?
2. What kind of issue have you had with scripts running the
shutdown and startups of postgres. Are these
scripts just a cron job doing what the /etc/init.d (or /etc/rc.d) automatic
startups do on unix-based servers?
3. Are you users informed that this is a daily occurrence?
4. What time in the 24-hour period are you performing this?
Thanks in advance,
