<Dt> Automated data grooming </Dt> <Dd> Frees up space on disk sets of backups by removing out - of - date backup data based on an administrator - defined retention period . One method of removing data is to keep the last backup of each day / week / month for the last respective week / month / specified - number - of - months, permitting compliance with regulatory requirements . One application has a "performance - optimized grooming" mode that only removes outdated information from a set of backups that it can quickly delete . This is the only mode of grooming allowed for cloud sets of backups, and is also up to 5 times as fast when used on locally stored disk sets of backups . The "storage - optimized grooming" mode reclaims more space because it rewrites the set of backups, and in this application also permits compliance with the GDPR via exclusion rules . </Dd> <Dt> Multithreaded backup server </Dt> <Dd> Capable of simultaneously performing multiple backup, restore, and copy operations in separate "activity threads" (once needed only by those who could afford multiple tape drives). In one application, all the categories of information for a particular "backup server" are stored by it; when an "Administration Console" process is started, its process synchronizes information with all running LAN / WAN backup servers . </Dd>
