Data snapshots play a significant role in data protection and DR.
Customers we speak to express their concerns about growing data sets
and fixed backup windows. What made disk to disk (D2D) backup
solutions popular is it solved the backup window challenge. What it
did not solve is it added more cost and complexity to IT. There is now
another box to mange. The box needs to grow with the data sets (after
all the data de-duplication is exhausted). Depending upon the D2D
vendor, expansion can be a painful and costly process. Companies
having deployed CloudArray and using its snapshot capabilities tell us
that it solves many of the challenges D2D backup solutions did not
address while providing similar benefits.
