Snapshot: Snapshots for data protection

Do you take snapshots? Do you use your storage system's snapshot capabilities? How often do you take snapshots? How long do you keep snapshots? Snapshot technology is widespread, but not everyone who has it uses it. Those who do use snapshots don't use them nearly as often as vendors suggest they should. Of the 87% of Storage readers who report having a system that supports snapshots, 59% take snapshots, while 41% don't use the capability. A healthy majority (67.2%) take only periodic snapshots, maybe one or two per day, vs. the measly 1.6% of respondents that report taking snapshots every 14 minutes or fewer. Once taken, snapshots are relatively short lived: 81.9% of them are deleted within a month.
