Backup – High-Performance Backup

Want to be sure you can restore your data in the event of a serious incident? The Backup service copies it to a safe location and ensures its integrity! Your data is backed up remotely every day via a high-performance backup service and stored on redundant systems within a secure data center.

Best practices to ensure the availability of your critical applications

Because your data is your most valuable asset, KDDI France supports you in preserving its integrity.

Combining Reliability and Performance

The Backup service ensures the protection of your data by performing a daily backup to a separate KDDI France site using dedicated equipment. It offers the following features:

  • Backup of physical or virtual servers
  • Backup on redundant physical disks (RAID)
  • Fast backup (up to 70% bandwidth savings)
  • Data encryption during transfer
  • Daily reporting

Our Backup service can be used independently of any other service, or to enhance KDDI France’s IaaS services (such as Agility).

A proven technology

The Backup service relies on EMC²® Avamar® technology (other solutions available), providing you with the following benefits:

  • Data deduplication at the source
  • Reduced backup window (by processing only modified data)
  • Reduced bandwidth usage
  • Optimized I/O on the storage system
  • Compatibility with most operating systems, including VMware and Hyper-V
  • Application plug-ins ensuring data consistency (MS SQL, Notes, Exchange, SharePoint, Oracle, etc.)

Secure Backups

Multiple mechanisms are employed to safeguard backed-up data and ensure its integrity:

  • Architectural redundancy: The backup systems, composed of multiple servers (nodes), benefit from dual protection against failures. At the server level, RAIN (Redundant Array of Independent Nodes — the equivalent of RAID5 for nodes) enables hot-swapping of a node. Disks are protected with RAID1 or RAID.
  • Integrity checks: The integrity of all backed-up data is verified once per day through a dedicated process (HFScheck). In addition, a snapshot of the system, taken twice daily, allows restoration to a healthy state in the event of human error or data corruption.

Data Deduplication

The data deduplication used by Backup is designed to optimize the volume of data to be transferred during backup.
During the initial backup, the data is split into segments. For subsequent backups, the system detects the segments containing modified data and compresses them before transfer.
Data deduplication is particularly well-suited for sites with limited internet bandwidth.

An optimized process

During a backup with Backup, only the modified data is transferred.
The data to be backed up is divided into chunks and compressed. These chunks are combined into composite chunks and sent to the backup server. The local cache is updated.
