Version 10.2 at a Glance
- Incremental reclamation of orphaned deduplication blocks. Improves deduplication compression multipliers and disk utilization because orphaned blocks are reclaimed sooner.
- Performance enhancements for local and remote replication. Replication is central to off-site storage of backups. Faster replication means lower costs for wide-area network bandwidth.
- New platform support for Fedora 20, openSuse 13.1, and Ubuntu 13.10. These platforms are now supported as both backup agents and backup servers. Many specialized agents (e.g. MySQL) are also available on these platforms.
WD Arkeia version 10.2 delivers features to enhance “hybrid cloud backups” for mid-sized IT environments. WD Arkeia v10.2 offers incremental reclamation of orphaned deduplication data blocks and additions to platform support with Fedora 20, openSuse 13.1, Ubuntu 13.10. This release was announced for backup servers deployed as software applications, physical appliances, and virtual appliances on February 6, 2014.
What is "block reclamation"? Over time, as retention periods for specific deduplicated backup sets expire, blocks to which the backup sets refer may become 'orphans.' Here, an 'orphan' is a deduplication block to which no current backup set refers following the expiration of other backup sets. While the impact of orphans is generally negligible at first, over time orphans can accumulate and adversely affect deduplication compression multipliers by creating disk storage overhead. Block Optimization includes the process to identify, consolidate, and reclaim disk space used by orphaned blocks.
Incremental Block Reclamation
Prior to WD Arkeia version 10.2, disk space would be reclaimed only after the complete block optimization process completed. If a backup or recovery process needed access to the WD Arkeia systems, block optimization would be interrupted and later resumed. Block reclamation was fast and efficient, but had to run to completion before disk space could be reclaimed.
With WD Arkeia version 10.2 block optimization progresses continuously and orphaned blocks are recovered incrementally. Unlike competitive products, no maintenance window has to be dedicated to the block optimization process. This new capability is available for all WD Arkeia backup servers, whether deployed as software, appliances, or virtual appliances.
Performance Enhancements for Local and Remote Replication.
Replication is central to off-site storage of backups. Faster replication means lower costs for wide-area network bandwidth. Replication performance improvements apply to both replication to tape and to disk.
New Platform Support
WD Arkeia updates support for several operating systems with version 10.2. Support includes Fedora 20, openSuse 13.1 and Ubuntu 13.10. These platforms are now supported as both backup agents and backup servers. Many specialized agents (e.g. MySQL) are also available on these platforms. See www.arkeia.com/platforms for the complete list of specialized agents supported.
