I am looking for a solution for backing up about 30 of my servers that are a mix of centos, windows 2003 and 2008 machines.
I have a san in another data center with a 1 Gig link between the sites that im going to be backing up onto so this is purely a disk based backup solution.
What I am ideally looking for is some open source software possible with a nice gui that will allow me to have a backup cycle with full backups on a monthly basis that go back 6 months and weekly backups that are saved for one month. I'm hoping for de duplication as well so if a file is saved on the first backup the software creates a symlink to it rather then saving the data again in all the proceeding backups. It must also be smart enough to know when a file is deleted that the file is moved to the latest backup it exists in and all symlinks to it are updated.
I was looking at bacula but im unsure if it can do the deduplication or something similar. If it can will someone be kind enough to point me at a decent guide as to how to do it.
If it does not can someone recommend another solution open source or not?
