Yes. It can also update/fetch RRDs created with 1.0.x. There are 3 RRD formats: 0001, 0002 and 0003. RRdtool 1.0: creates 0001, fetch/update 0001 RRDtool 1.1: creates 0002, fetch/update 0002 (this branch never really went public) RRDTool 1.2: creates 0003, fetch/update 0001 or 0003 RRDTool 1.3: creates 0003, fetch/update 0001 or 0003 So you see the underlying RRD format did not actually change from 1.2 to 1.3 If you still have some RRDTool 1.0 servers then they cannot read or update RRDs created by RRDTool 1.2 or 1.3 though. RRD formats 0001-0003 are architecture dependent (you cannot copy them between different-endian operating systems, or between 32bit and 64bit Operating systems). Version 0003 adds the HW type RRAs. Apparently, I hear that RRDTool 1.4 will introduce a new RRD format 0004 which is architecture-independent...
