Whether you use Oracle, Microsoft SQL Server, MySQL, IBM DB2, PostgreSQL, or MongoDB, our comprehensive data management platform reduces risk with granular restores that minimize — or eliminate — downtime. We then verify that the compression is now set to lz4. AppAssure/RR combines inline deduplication and compression with incremental-forever and change-block tracking technologies to reduce the amount of backup data that would otherwise … Since the data file was only moved between backups, it was not back upped a second time hence the deduplication ratio of 1:2.
