Question 3

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.
The nature of the customer's business requires frequent lookups of historical data, often beyond the Avamar
2-month retention period. Therefore, quick recovery of files from tape is required. Compliance requirements mandate tapeout be performed on a weekly basis. The customer is considering Avamar Data Transport (ADT) or Avamar Tape Out (ATO).
Which tapeout solution is best suited for this environment?

A. ADT due to its ability to write deduplicated data to tape and its ability to process several TBs per day B. ATO due to its ability to write deduplicated data to tape and its ability to process several TBs per day C. ATO due to its file level recovery capabilities from tape and its ability to process several TBs per day D. ADT for its file level recovery capabilities from tape and its ability to process several TBs per day

Correct Answer: C
