Does Unitrends use File or Block-based backups?</p> <h3 data-id="description">Description</h3> <p>What is meant by block level backup? Does Unitrends use File or Block-based backups? For example, if a change is made to a file do we replicate the change blocks only or whole file?</p> <h3 data-id="cause">Cause</h3> <p>N/A</p> <h3 data-id="resolution">Resolution</h3> <p>Unitrends blends file-based backups with block-based backups depending on operating system and content.</p> <p>File-based backup tends to be more flexible, tends to handle applications better, and tends to allow greater selectivity in terms of what is backed up. Block-based backup is also quite often the only game in town for protecting host-level virtualized environments (such as VMware with VADP)</p> <p>The Unitrends Agents combine file-based backups for most common files types. Application-aware, block-level backups are used to capture differential backups for SQL, Exchange and HyperV. Also, block-level backups are used for agentless VMware host backups.</p> <h3 data-id="third-party-sources">Third-Party Sources</h3> <p> </p> </article> </main>
