Microsoft says its Azure Backup service is about to get faster, with lower cache demands and increased data retention.
Keeping track of changes via Update Sequence Number Journal, Azure can identify changes faster thus speeding up backups. “We’ve seen up to a 50% reduction of backup times in volumes with two million files utilizing this optimization,” said Microsoft’s Giridhar Mosay, Program Manager for Cloud and Enterprise on the Azure Blog.
Alongside this, Microsoft has introduced a new algorithm to Azure Backup that utilises far less disk space when computing metadata. Using the algorithm, Microsoft has reduced the required cache space of 15% volume size down to 5%.
“In our internal tests with large volumes, we are now seeing less than 5% cache space requirement which is a 3X improvement. To that effect, we are updating our requirement for cache space accordingly to be less than 5% of the size of data being backed up,” Mosay said.
Additionally, Microsoft has increased the number of recovery points for cloud backups, from 366 to 9999. “This enables flexible retention policies to meet stringent compliance requirements such as HIPAA for large enterprises” wrote Mosay.
