Hey
That sounds like what I would need to do. Could you provide a few
more details about how this was accomplished.
Thanks

John,
We accomplished this using an inline filter to capture the
checksum and size for the entire dump to tape. Then we re-read
the tape to see if the tape generated the same checksum and size.
That is probably about a good as you are going to get.

Hey Again
Thanks for the input. but what I am wanting to check for is CRC
errors and block errors. The backups are written to tape and I would
like a way to verify the data on the tape as compared to the data on the
server. I may be way off here but I just want to be sure I am getting
reliable backups.
Thanks

Hello
I have a question regarding backups on Postgresql 7.4.7-2. We are
currently using a Progress database and will be moving over to Postgres
this month. In Progress there is a way to verify your backups does
Postgres have anything similiar or is there other ways to accompplish
this. I am currently writing backup and other utility scripts and would
like to incorporate this into my program.
I wrapped my backup in a bash script, and that seems to catch errors.
something like:
if !(
/data01/pg/bin/pg_dump dbname > dbname.sql
);
then
cat "backup failed"|mail -s "backup failed" yourname@xxxxxxxxxxxxxx;
fi
To test this, I corrupted a table in a test database to force a hard
failure, and it sent an email. Don't know if it's a comprehensive test,
but it seems to work for us.
