Calculate disk for backup

Calculate disk for backup

The customer has the list of servers that need the backup. This list has a total of 18 servers and 6TB. Retention is one year. Using disk with DEDUP.

To keep the monthly backups for a year, how much disk will it take?
How do I make these calculations?

    ...it's the "how long is a piece of string" question. the link above MIGHT help (as I mentioned) but I haven't seen much in the way of a 100% accurate dedupe calculator. Read the BE documentation and they should be able to give you a 30-40% compression/dedupe ratio for instance.

    But it's all dependant on similar OS's, type of data etc.

      This link does not help much. You have nowhere to report retention.

      Any other links or documents?

      I thank the answer.
