Kevin, Thank you for the reply. I guess 60Sec is a valid option if this is the 'time period' we can tolerate. PS pg_clearxlogtail I tried to lookup more info about it but could not find much. With regards to pglesslog I found the site which hosts the project, seems interesting. My question is does it copy the logs as well as compresses it, because there is an example: archive_command = 'pg_compresslog "%p" /"%f"' Is this instead of using 'cp'? Thank you very much Best regards Renato Renato Oliveira Systems Administrator e-mail: renato.oliveira@xxxxxxxxxxx Tel: +44 (0)1763 260811 Fax: +44 (0)1763 262410 http://www.grant.co.uk/ Grant Instruments (Cambridge) Ltd Company registered in England, registration number 658133 Registered office address: 29 Station Road, Shepreth, CAMBS SG8 6GB UK -----Original Message----- From: Kevin Grittner [mailto:Kevin.Grittner@xxxxxxxxxxxx] Sent: 09 April 2010 15:22 To: Renato Oliveira; pgsql-admin Subject: Re: archive_timeout - good indication Renato Oliveira <renato.oliveira@xxxxxxxxxxx> wrote: > What would be a good indication for 'archive_timeout' on a busy > server? The maximum amount of time for which you can tolerate lost transactions in case you need to use the backup for crash recovery. Note that you need to balance that need against the space requirements of the WAL files. You can mitigate the space problem by using pg_clearxlogtail or pglesslog. -Kevin -----Original Message----- P Please consider the environment before printing this email CONFIDENTIALITY: The information in this e-mail and any attachments is confidential.
