![]() By contrast differential backups are “pay now” in that they consume more resources to perform, but it’s easier to restore from them.ĭecide if you want to backup your data to a public cloud, a private cloud or bothīefore you start deciding whether or not you want to back up your data to a public cloud, you’ll first need to check if your data is suitable for storage in the public cloud. This means that incremental data backups are essentially “pay later” as they are fairly quick and easy to do but it can be a pain to restore from them. Differential data backups only back up data which has changed since the last full backup. Incremental data backups only back up data which has changed since the last data backup (regardless of whether it was full or incremental). The standard approach is to run periodic full data backups, preferably out of hours and to supplement these with incremental and/or differential data backups. In the real world, this would demand far too much in the way of time and resources. ![]() In an ideal world, all data backups would be full backups. This approach can vastly increase your options for restoring your data promptly.ĭecide how often you need to take full backups Backup to two physical devices and send one to a vendor which can both upload the data to a cloud and keep the physical device secure (or send it back to you to be securely stored in another off-site location). They only really have value if you’re uncomfortable relying on your network connection, for example if you’re in a remote area.Įven in that situation, however, you could still split the difference and get some benefit from the cloud. These days many companies see physical backups as being more hassle than they’re worth. Safe meant protected from environmental hazards such as fire and flood as well as safe from criminals. You then sent one off-site and kept the other one in a safe place. In the old days, it was taken as read that data backups meant backing up to physical devices. Decide if you still need to back up to a physical device
