Data Deduplication Provides 61:1 Compression for VMware Images
Ipswich backs up a wide variety of data to the ExaGrid system, including SQL, file data, and VMware images. The Council backs up its VMware images directly to the ExaGrid system and has been receiving data deduplication rates as high as 61:1.
“We are expanding our use of VMware and it would have been a real challenge to put the images onto tape. ExaGrid’s data deduplication technology does a fantastic job at compressing our VMware images, and our recovery times have really improved. We can recover a VMware server in about ten minutes. With tape, recovering the same VMware server would have taken half a day,” said Gaskin.
Gaskin noted that restoring data from the ExaGrid is significantly faster than with tape. “With tape, we had to retrieve the right tape from our offsite storage site, catalog it and read the file in. The whole process could take hours and hours. However, restoring data from the ExaGrid takes no time at all. It’s far more efficient and it frees up our time to focus on more important things,” said Gaskin.
Pergala paşvekişandina-based dîskê ya ExaGrid ajokarên pargîdanî bi veqetandina daneya-asta-herêmê re digihîne hev, çareseriyek-based dîskê peyda dike ku bihatir e ji tenê piştguhkirina dîskê bi veqetandinê an karanîna nermalava hilanînê ya li ser dîskê. Dabeşkirina patentkirî ya ExaGrid-ê li ser asta deverê cîhê dîskê ku hewce dike bi rêzek 10:1 ber 50:1 kêm dike, li gorî celebên daneyê û heyamên ragirtinê, bi hilanîna tenê tiştên yekta li ser paşvekişandinê li şûna daneyên zêde. Deduplication Adaptive veqetandin û dubarekirinê bi paşkêşan re paralel pêk tîne. Ji ber ku dane li depoyê têne derxistin, ew ji bo vegerandina karesatê (DR) li malperek ExaGrid-ê ya duyemîn an ewrê gelemperî jî tê dubare kirin.
