Live data presents a number of challenges for database backup, particularly in the case of database files that are continuously being written to. Ensuring no changes are lost in the backup process can require considerable configuration. Blueberry can apply a number of optimization techniques to ensure continuous backup of live data.
Backing up Web or database servers can also be tricky. Traditionally, a list of folders is written to backup but this leaves data open to human error. A full backup is the failsafe option but with storage space at a premium, solutions that combine one full backup with subsequent incremental backups offer a cost-efficient alternative. One example is the incremental snapshot system provided with the Cloud-based Amazon EBS service.
Backing up in virtual environments demands a different approach from physical servers. The critical factors are storage availability, configuration and management. If these are properly addressed, the benefits can be considerable. Blueberry has experience in engineering unusual backup systems in virtual environments and mirroring virtual machines from one server to another.
Achieving high levels of redundancy usually requires two servers. This can be costly and companies should consider whether instant redundancy is really vital for their business. With solutions such as Amazon EBS, for example, a new system can be set up from a snapshot in just 30 minutes without the need for two servers. Redundancy of database servers is more complex to configure and usually requires some level of mirroring or replication. Blueberry Consultants leverages a range of tools and techniques to optimize this process. These include custom compression, encryption, data deduplication and incremental transfer approaches.
