QUESTION 58

A customer has four EMC Avamar servers located in a centralized disaster recovery site, each receiving replicated data from several remote sites. Several client backups are in the range of 1 - 4 TBs per dataset with file counts of 2 - 4 million files. Due to capacity limitations, Avamar retention value is limited to two months and tapeout is being used to provide extended retention of up to five years.
