Telecloud Backup – high-performance protection
Service Introduction Video
Are you doing enough to protect your data?
Because your data are your most precious resources,
KDDI France supports you in preserving the integrity of your digital investments without compromising on security.
Combining reliability and performance
Telecloud Backup safeguards your data by backing them up daily to a specific KDDI France site using dedicated facilities. The service offers the following capabilities:
- Backup of data held on physical or virtual servers
- Backups stored on a RAID (redundant array of independent disks) system
- High backup speeds (saving up to 70% of bandwidth)
- Data encrypted during transfer
- Daily reporting
Telecloud Backup can be used independently of any other service or to bolster KDDI France’s IaaS services such as Telecloud Agility.
Proven technology
Telecloud’s backup and restoration service is underpinned by the EMC²® Avamar® technology (other solutions are also possible, like COHESITY), offering the following benefits:
- Data deduplicated at source
- Reduced backup window (by only processing modified data)
- Reduced bandwidth
- Optimised I/O on the storage system
- Compatible with most operating systems, including VMWare and Hyper-V
- Plug-in apps to ensure data consistency (MS SQL, Notes, Exchange, SharePoint, Oracle, etc.).
Secured backups
Several mechanisms are deployed to safeguard the backed-up data and guarantee their integrity:
- Redundant architecture: the backup systems are composed of several servers (nodes) and feature dual failure protection. At server level, a RAIN system (Redundant Array of Independent Nodes, the equivalent of RAID 5 for nodes) enables hot node replacement. The disks are either RAID 1 or RAID configured.
- Integrity check: the integrity of all backed-up data is checked once a day by a dedicated process (HFS check). A snapshot of the system is also taken twice a day so that the volume can be brought back to a healthy state in the event of a human error or should data become corrupted.
Data deduplication
The data deduplication process used by Telecloud Backup aims to optimise the volume of data to be transferred during the backup process.
The first time the backup is performed, the data are split into blocks. During subsequent backups, the system detects the blocks containing modified data, compresses them, and then transfers them.
Data deduplication is particularly suitable for sites with a limited internet bit rate.
An optimised process
The Telecloud Backup process only transfers modified data, which it identifies by comparing them with a local client-side cache.
The data to be backed up are split into blocks and compressed. These blocks are then combined to form composite blocks and sent to the backup server. The local cache is updated.
Performance in figures
The following table indicates the data volumes actually transferred in comparison with the total volumes backed up.
| Types of data | Quantity of main data backed up | Quantity of data transferred daily | Daily deduplication rate |
|---|---|---|---|
| Windows file systems | 3573 GB | 6.1 GB | 586:1 |
| Combination of Windows, Linux and Unix file systems | 5097 GB | 11.7 GB | 436:1 |
| Technical files on NAS server | 3265 GB | 24.2 GB | 135:1 |
| Combination of 20% databases, 80% file systems (Windows and Unix) | 9583 GB | 80 GB | 120:1 |
| Combination of Linux file systems and databases | 7831 GB | 104.2 GB | 75:1 |
