I have jobs that get 1MB/s and other jobs that get 25MB/s.
I spool in 50GB chunks. For full backups, network transfer rates hover around 5MB/s, while streaming to tape varies: * 35MB/s -- development hosts (lots of source code) * 22MB/s -- home and project directories (mixed code and binaries) * 16MB/s -- database server (mostly binaries) I suspect the median speed is about 22MB/s, but I've never subjected my Bacula logs to statistical analysis. :-) Overall speed (spooling, streaming to tape, writing attrs to database) is around 3MB/s. Oh, yeah, this is 2.0.3 (server and all clients) to a Dell PowerVault 122T with an Ultrium LTO-2 drive. -- Paul Heinlein <> [EMAIL PROTECTED] <> http://www.madboa.com/ ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
