#SYNCOVERY SYNTHETIC BACKUP FULL#
Each new incremental backup will be synthesized and will maintain an up to date copy of a full backup. The bottom line is after the first full backup you need to take only incremental backups without taking a full backup every time. Whereas with a synthetic backup technique in place, the system will only take incremental changes, transfer them over the network pipe and then run a special program at the storage location to apply those changes to the previous full (or synthetic) backup. It is due to the fact that the traditional approach of taking a full volume backup requires transferring all used blocks of data from the volume to the backup location. Less data, which is translated in to less network traffic, will be flowing through the pipe in the case of synthetic backup. Figure 1 shows the steps involved in taking a traditional full backup and a synthetic backup. This backup procedure is called “synthetic” because it is not a backup created from original data. Instead, a synthetic file is merged or “synthesized” by a specialized application program from the original file and one or more modifications to it.įigure 1: Conceptual representation of Synthetic versus Full backup
The expression “synthetic” in this context refers to the fact that the assembled file is not a direct copy of any single current or previously created file.
Since this type of backup is synthesized from a full backup, hence the name. It involves one regular full backup (only the first time) and from that point onwards periodic incremental backups are applied to the first full backup. Synthetic backup is an alternative to creating full backups from periodic incremental backups. It also offers an edge over conventional file system backup techniques during system backup and restore. Synthetic backup is one such DR best practice that provides effective data protection at a lower cost of operation. With well thought planning in deploying IT infrastructure and implementing best practices for maintaining corporate data, such as Disaster Recovery (DR) planning for data protection and security companies can save significantly and improve their profit margins. Given the fact that data protection is a primary concern for companies of all sizes, it requires significant investment (depending upon the company size) and surely is a contributing factor to the company’s profitability. Data protection is becoming very complex and requirements for availability are increasing every day.
Enterprises big and small have seen their data grow exponentially over the years.
