Hi all, Can I do a consistent file-system-level backup using the following procedure: 1) SELECT pg_start_backup(...) 2) rsync postgres data dir to another server 3) SELECT pg_stop_backup() 4) rsync pg_xlog directory From what I understand this should be similar to running pg_basebackup using the -x parameter, correct? One caveat seems to be that wal_keep_segments should be set "high enough". Can anybody tell what "high enough" usually is? Thanks in advance for you help! Best regards, Juergen
