Snapshot doesn't work well when you're already backing up data with another software. For example, if a customer has backup software in their environment and wants to use Snapshot alongside it, that won't work effectively. It will bubble up back-end storage space. Also, if a customer frequently deletes data, Snapshot will take up a lot of space. For example, if they write one terabyte of data and delete it at the end of the day, and then rewrite it the next day, scheduling a snapshot in that scenario will cause it to take up a lot of space. So, in scenarios where you need data protection, you have to use NetApp Snapshot exclusively and not use any other product for that. Secondly, where there's a lot of data deletion or overwriting, NetApp's Snapshot will not be an effective way to provide backup and recovery. I've told a lot of my customers this because I've seen the problems firsthand. They call me saying their storage is full, and I find that they are deleting and then copying the data repeatedly. I ask them why they're doing it, and they say it's their daily work to archive, delete, and copy. So I have to disable the Snapshot and tell them that if they're already copying the data with other tools and deleting it, then the data isn't important, and they don't need a snapshot or backup of it. For additional features: NetApp is already a visionary company. They analyze their deployed products and change them according to customer requirements. To me, it's not about technical improvement, but the price factor is important for selling the product. So, the price factor is challenging. Snapshot is a ten out of ten. If the whole product needs improvement, I think one feature they could add is an alarm or notification in the NetApp management console if you're frequently deleting data or using a volume for backups. The alarm would indicate that you don't need to enable Snapshot in that case. That kind of alarm, notification, or indication could be added. If a customer is deleting data very frequently, there should be a mechanism to notify the administrator. A message should be triggered if the customer has enabled Snapshot, advising them to disable it, as it will use unnecessary storage. This would be a helpful feature. Otherwise, administrators or deployers should know to discuss this with the customer during deployment. They should advise the customer not to enable Snapshot on volumes where they frequently delete and copy or archive data.
