I googled a bit for an incremental or differential way to backup postgresq. I was hoping there would be switch on pg-dumpall that would backup all tupples added since some date. Doesn't look like it exists. I did find a backup method using the WAL files on the file system at http://www.oreillynet.com/pub/a/databases/2006/07/13/lamp-data-protection.html?page=last I also found this: http://www.postgresql.org/docs/8.1/static/backup-online.html I seem to remember around pg 7.x that file system level backups were very bad. Now, it seems the pg 8.x way is to allow the admin to take advantage of file system tools look tar, cpio, dump, etc. I was wondering if there any other recommendations beyond what is mentioned in the docs above? -- David Bear phone: 602-496-0424 fax: 602-496-0955 College of Public Programs/ASU University Center Rm 622 411 N Central Phoenix, AZ 85007-0685 "Beware the IP portfolio, everyone will be suspect of trespassing" ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
