We have about 5 servers spread out throughout the country: 2 Centos 4.4, 1 Red Hat and 2 windows machines- looking for some good ideas for a back-up solution. Our servers hold a lot of data, but only a small portion of it is crucial on any given day. That crucial portion is always changing (for example, this week the crucial files all relate to November- current and previous projects, and the next project in early December). What we need to have is a backup solution that would allow us to roll back to any given day (about four weeks of daily history). Bare-metal backups are a must. Our ideal solution would be to find someone who could design and implement a system for us. All ideas and suggestions are welcome.
