What "partial files" do you speak about? I'd like to know, as we soon start doing WAL copies. > rsync Incredible. You mean you make the hard link both on client and server, and afterwards transfer with rsync? That only works for postgresql <8.3, right? As I understand, 8.3 will reuse the space from updated tuples and therefore lots of changes in-between will be done. Or do you use "cluster" to sort the data before copying? But then if one older record is deleted, all further data will have to be transfered anyway. I'm just wondering where the savings come from. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0660 / 415 65 31 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: wwwkeys.eu.pgp.net Key-ID: 1C1209B4
