R1Soft takes a slightly different approach to server backup than most traditional backup companies. While traditional, incremental backup products allow you to backup your data at the file level, Server Backup Manager (SBM) enables you to perform backups at the block level.
So what's wrong with performing backups at the file level? First and foremost, file-level backups tend to consume huge amounts of system resources, causing the backup application itself to compete with processes critical to the services the systems are supposed to provide. Aside from performance issues, traditional backups could also result in major limitations. For instance, it's nearly impossible to perform true bare-metal restores with file level backups.
As you may have guessed from the title of this post, block-level backups don't deal with all of the deficiencies that come with their file-level counterparts. Let's take a closer look at how block-level backups can solve many of the pains often associated with performing backups at the file level.
