Click the Calculator icon in the upper left-hand corner. In an EMC NetWorker environment,
the customer is backing up 500 GB per day. The 500 GB is comprised of 35,000 very large
files. According to EMC best practices, approximately how large will the Client File Index
(CFI) be?
A.
6 MB
B.
4 MB
C.
8 MB
D.
10 MB
Index catalog size = (n+(i*d))*c*160*1.5
where:
n = number of files to backup
d = days in cycle (time between full backups)
i = incremental data change per day in percentages
c = number of cycles online (browse policy)
The statistical average is 160 bytes per entry in the catalog.
Some of the PDF’s like command references recommend 200 Bytes per saved file instance in the index.
Multiply by 1.5 to accommodate growth and error
((35000*160) /1024/1024)*1.5 = 8.01 MB
