Ask any expert about backup and disaster recovery (BDR) and you’ll quickly learn it is no longer what it used to be. There are more options out there than ever, and figuring out what will work best for your small to midsize business (SMBs) customers up front — before they make the investment — is essential. Image-based backup, also known as sector-based backup, is emerging as a top choice for channel partners and their SMB clients today, and that’s because it makes up for the limitations of competing alternatives in a number of ways.
In a nutshell, image-based backup efficiently records an image of the entire server, allowing for the complete system to be restored very quickly when needed. Incremental backups are then made going forward. All backups are saved to a network-attached storage device or appliance, or even to removable storage such as rotating media. The backups are then archived offsite using automated software, and can still be archived by physical means, often using rotating media.
