Full backups take 4-6 weeks for 500 TB now. > If you backup 500TB for about 1,5 month then depending on requirements, you should optimize your setup ASAP. You can optimize in a dozen different ways. First (as always) you need to find your bottleneck! The point where all your backup slows down. It could be a network, CPU, memory, database (when not using attrib spooling and you backup a massive number of files), data source, etc, etc. Doing optimization without backup flow analysis is a waste of time and effort. best regards -- Radosław Korzeniewski rados...@korzeniewski.net
