We have several small remote offices, all with less than a handful of PCs at each site. Due to the location of the sites, they either have dialup internet connections or at best 512/128 or 256/64 ADSL connections. None of the sites have file servers, so all user data is stored on each PC. I've been trying to investigate some way to effectively backup the data at each of the sites. Because of their narrow band internet connections I don't think remote backup will work. Backing up to an external HDD is an option but brings with it management and data security issues. Is there any technology out there that can provide me with a manageable yet secure backup solution?
