PHC Shortens Backup Window with ExaGrid
PHC backs up hundreds of terabytes of patient data and runs incremental log backups every hour of the day. The organization also runs weekly, monthly, and yearly fulls and must keep the data for seven years.
“We’re a 24/7 shop. The backup window was always tough for us no matter what, but now we are making it quite easily using ExaGrid. We’re beating it by hours compared to when we were using EVault,” said Bowes. Bowes is pleased that the deduplication ratios have doubled with ExaGrid. “At the highest, we’re getting 22:1, which is much better than the 5:1 we experienced with EVault; 10.5:1 is the average ratio achieved, which is excellent.”
ExaGrid’s turnkey disk-based backup system combines enterprise drives with zone-level data deduplication, delivering a disk-based solution that is far more cost effective than simply backing up to disk with deduplication or using backup software deduplication to disk. ExaGrid’s patented zone-level deduplication reduces the disk space needed by a range of 10:1 to 50:1, depending on the data types and retention periods, by storing only the unique objects across backups instead of redundant data. Adaptive Deduplication performs deduplication and replication in parallel with backups. As data is being deduplicated to the repository, it is also replicated to a second ExaGrid site or the public cloud for disaster recovery (DR).
