A different encryption key is used for every job session therefore encrypted data blocks sent to deduplicating storage appliances appear as different even though they may contain duplicate data. Also, if you enable encryption for an existing job, during the next job session Veeam Backup & Replication will create a full backup file.Įncryption also has a negative impact on deduplication ratios if you use a deduplicating storage appliance as your target. You may therefore wish to start a new chain so that the unencrypted previous chain can be separated and secured by other means. If encryption is enabled for an existing backup job, Veeam Backup & Replication does not encrypt the previous backup chain created with this job. One important point to realize is that encryption in Veeam Backup & Replication is not retroactive.

However, there are some caveats and nuances that need to be understood before enabling backup encryption. Encryption within Veeam Backup & Replication operates at the following levels: Backup job, Backup copy job, VeeamZIP and for Tapes in media pools. Veeam Backup & Replication offers inbuilt encryption to protect data in backups so it is important that organizations consider using this feature. Veeam Backup EncryptionĮncryption is the key tactic employed in most ransomware attacks, so let’s start by looking at Veeam encryption opportunities to beat cyber criminals at their own game. In this article we will look at some key areas for consideration to ensure backups are kept secure, and to avoid them becoming an easy source for any data breach campaigns. Often incidents involving data breach are significant enough to make the front pages, causing irreparable reputational harm to the organizations involved.

In addition, exposed PII can used by criminals to conduct identity theft, blackmail, stalking, or other crimes against their victims. The definition of PII is broad but can be summarized as information that if lost, compromised, or disclosed could result in substantial harm, embarrassment, inconvenience, or unfairness to an individual. Backups play a key role in defense against cyber-attacks, potentially allowing systems to be restored to a known safe operational point in time yet they also present a ‘one stop shop’ for the acquisition of PII.

Cyber-attacks typically have two high level objectives, the first being to cripple business operations by encrypting vital production data, and the second more recent trend is the capture and breach of Sensitive Personal Identifying Information (PII).
