In addition to keeping the backup files themselves safe from attackers, companies should also ensure that their data catalogs are safe.

Palatt suggests that companies keep different types of backups, such as full backups on one schedule combined with incremental backups on a more frequent schedule. "All of a sudden you come in and all your iterations have been overwritten because we only have three, or four, or five days." Two were overwritten, but the third day was still viable." If the ransomware had hit over, say, a long holiday weekend, then all three days of backups could have been destroyed. "In one case, our client had three days of backups. "In many cases, enterprises don't have the storage space or capabilities to keep backups for a lengthy period of time," says Palatt. Some backup technologies only save changed and updated files or use other deduplication technology to keep from having multiple copies of the same thing in the archive. This does increase the cost of backups since it requires substantially more storage. Use either physical write-once-read-many (WORM) technology or virtual equivalents that allow data to be written but not changed. You just go back to the last good version of the file before the attack.Īnother way to protect backups is to use storage that can't be written over.

Technology that saves continuous incremental backups of files also means that there's no loss of data when ransomware hits. Even if ransomware strikes, and the encrypted files are backed up, the backup process just adds a new, corrupted version of the file-it doesn't overwrite the older backups that are already there. For example, Office 365, Google Docs, and online backup systems like iDrive keep all previous versions of files without overwriting them. Some cloud-based platforms include versioning as part of the product for no additional cost.

If the encrypted files get written to the local backup solution and then get replicated to the cloud, that doesn't do you any good."

"But ideally, if someone has both, they don't cascade. "We do see some of our clients that have on-prem backups that they run themselves, as well as cloud-based ones," says Jeff Palatt, vice president for technical advisory services at MoxFive, a technical advisory services company.

Keeping an "air gap" between the backups and the production environment is critical to keep it safe from ransomware-and other disasters. Keep the backups isolatedĪccording to a survey by Veritas released last fall, only 36% of companies have three or more copies of their data, including at least one off-site. Here are eight steps to ensure a successful recovery from backup after a ransomware attack. Most importantly, backups should be well-tested. Part of the reason is the lack of backups-specifically, the lack of usable backups.īackups must be safe from malware, quick and easy to recover, and include not just important files and databases but also key applications, configurations, and all the technology needed to support an entire business process. According to a ransomware survey report released in June by Keeper Security, 49% of companies hit by ransomware paid the ransom-and another 22% declined to say whether they paid or not.
