[rdiff-backup-users] Database backups: AssertionError: Found too many current_mirror incs!

[Jeff Blasius]

Hello all,
I just want to verify what I think is happening. It looks like if the 
database file does not change for
three backups it will not backup the file again?? If the file does 
change will rdiff-backup
back it up?

Also, is there a better way to do this?

Thank You,
             jeff

Here is my code:
#!/bin/bash
touch /tmp/postgres/postgres_dump.sql
chown postgres.postgres -R /tmp/postgres
chmod 700 -R /tmp/postgres
su - postgres -c "pg_dumpall > /tmp/postgres/postgres_dump.sql"
rdiff-backup --remove-older-than 1M /system/backups/rdiff_postgres/
rdiff-backup /tmp/postgres/ /system/backups/rdiff_postgres/
chmod 600 /system/backups/rdiff_postgres/postgres_dump.sql
rm -f /tmp/postgres/postgres_dump.sql

Here is the dump:

/etc/cron.daily/dump_postgres.sh:
