On-line backup

Hi Tom,

Is this 2003 advice still relevant with postgresql 8.1.0? Our b-tree
indexes corrupt pretty often on our production server running 8.1.0 and we
are grasping for a solution. We perform online backups like this: In
addition, we archive the transactions and replay them for PITR.

/usr/local/pgsql.v810/bin/psql -p 5442 -d postgres -c "SELECT
pg_start_backup('share.sqldumps.Linux.pgsql.serf.base.backup');"
sleep 20
/bin/tar -zcvf /sprj/sqldumps_Linux.pgsql_serf5442/base.backup.serf.`date
'+d%m%d%Y'`.tar.gz /anothershare/Linux.pgsql/serf5442/*
sleep 30
/usr/local/pgsql.v810/bin/psql -p 5442 -d postgres -c "SELECT
pg_stop_backup();"
