I am the only Storage Administrator for a medium-sized enterprise. We have over 280TB of storage on various vendors’ equipment. When I first started, we were running all of our backups through a silo with LTO1 drives in it. We couldn’t ever back up all we needed to in the backup window we were given. We finally upgraded to LTO4 drives after several failed attempts to recover critical data and servers (Along with complaints about network slowdowns, which of course came right to me, regardless of the ACTUAL cause, but I digress). Now, we are able to meet our windows with time to spare.
