High-Rely DeltaSync File-Level Backup Technology Introduced

Highly Reliable Systems, Inc. have announced at the ASCII Group Success Summit availability of NetSwap firmware release 2.13.

This update includes the DeltaSync technology, which enhances synchronization functionality for NetSwap and RAIDFrame server backup appliances. DeltaSync is a file-level tracking feature that queues changes in memory, and promotes significantly improved synchronization times between company’s devices and their targets.

“A key feature of our products is our Automatic Mirroring Technology (AMT), which allows our backup systems to be continuously connected while creating automatic backups onto removable media. Our new DeltaSync feature was designed in direct response to the needs of our customers using today’s larger HDDs” explained Derry Bryson, senior software engineer, Highly Reliable Systems. “High-capacity HDDs translate into longer rebuild times using block-by-block mirroring technology that copies the entire disk – even if only a small portion of the data changed. DeltaSync copies only the data that has changed, leading to rebuild times that are a fraction of what they were using mirroring.“

DeltaSync offers a straight-forward user interface, with easy to understand features and simple configuration options. Synchronization can occur in real time, or on a set schedule. If synchronization is interrupted, it will rescan and restart the process without concern for loss.

Tom Hoops, CTO, Highly Reliable Systems, had this to say about the technology: “Our DeltaSync feature greatly shortens time to re-sync a degraded RAID-1 (mirror) volume when a media has been swapped. The addition of this feature allows our Automatic Mirroring Technology that has been used for years to provide a hardware-only backup method that keeps pace with today’s growing HDD sizes.“

Also available in this free firmware update is the NetSwap Locator software tool, which detects company’s backup appliances visible on the network and enables faster access for configuration tasks. Complete details of this update are documented in the change log:

Release 2.13 (February 26, 2015)

Added DeltaSync feature as an alternative to using mirror disks – a smart sync that copies only changed data
Default IP mode is DHCP+STATIC which is a dual IP mode with DHCP plus a static IP that defaults to 192.168.1.50 for backwards compatibility
Added ‘action URLs and programs’ to facilitate safe removal of disks without logging in to the web UI
Added network detection feature to allow NetSwaps to be automatically detected by the NetSwap Locator software (available on website)
Updated Realtek network driver to version r8168-8.039.00 to fix possible network disconnections with some chips/motherboards
Added Tehuti Networks 10GE tn40xx-0.3.6.11.1 driver
Modified NAS share mode to minimize network disconnects when swapping disks
Updated Samba to fix code execution vulnerability CVE-2015-0240
