[GENERAL] : Checksum ERROR when restoring Online Backup
Hello Everyone, I am testing the Online Backups of our production databases ( this is part of our disaster recovery plan ). After restoring the Online Backup, we tried to bring up the cluster and ended up with the following error - 2011-09-23 07:29:04 CDT [24092]: [1-1] FATAL: incorrect checksum in control file. Does this message mean, the Online Backup is corrupted or invalid ? Normally, we get recovery related error messages. This is the first time we are facing a problem like this. Please help as this is critical for us. Thanks Venkat
Re: [GENERAL] : Checksum ERROR when restoring Online Backup
Apologies - I did not mention complete details of PG and OS - Postgres 9.0.1 Production Operating System version where Postgres is running is as follows - Linux *prod-server* 2.6.18-194.17.1.el5 #1 SMP Mon Sep 20 07:12:06 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux The server version where I restored the production backup is as follows - Linux *backup-server* 2.6.18-194.3.1.el5PAE #1 SMP Sun May 2 04:42:25 EDT 2010 i686 i686 i386 GNU/Linux I read some where that, Postgres datafiles are not architecture independent. Please help !

They (the WAL files) are not, and it looks like you're trying to restore a 64-bit version onto a 32-bit server. That's not going to work. A pg_dump/restore works of course, and if you need replication then Slony can handle this. -- Richard Huxton Archonet Ltd -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Thanks Richard ! I realized that, I was restoring on an 32 bit server.
