Greetings, >The short answer is 'no'. There are complications around this, >particularly at the edges and because files can be written and rewritten >as you're reading them. >Basically, no file with a timestamp after the >checkpoint before the backup can be omitted from an incremental backup. what you have written above applies to oracle/db2 too. In case you are not aware, during backup, those products have a mechanism to save the image of any changing block as it existed before the start of the backup. that is used to reconstruct the PIT image of the block. Anyhow looks like this can't be done in PG. thanks all. -- View this message in context: http://www.postgresql-archive.org/Incremental-Level-1-backup-in-PG-tp5951072p5951148.html Sent from the PostgreSQL - general mailing list archive at Nabble.com.
