Checking A RepositoryAppAssure 5 provides the ability to perform a diagnostic check of a repository volume when errors occur. Core errorscould be the result of it being improperly shut down, a hardware failure, and so on.NOTE: This procedure must only be performed for diagnostic purposes. For example, in the event of hardwarefailure, improper shutdown of the Core, and so on.To check a repository:1. On the Configuration tab, click Repositories, and then select the right angle bracket (>) symbol next to therepository you want to check.2. In the Actions pane, click Check.The Check Repository dialog box is displayed.3. In the Check Repository dialog box, click Check.NOTE: If the check fails, restore the repository from an archive.Deleting A RepositoryTo delete a repository1. On the Configuration tab, click Repositories, and then select the right angle bracket (>) symbol next to therepository you want to delete.2. In the Actions pane, click Delete.3. In the Delete Repository dialog box, click Delete.CAUTION: When a repository is deleted, the data contained in the repository is discarded and cannot berecovered.Managing SecurityThe AppAssure 5 Core can encrypt agent snapshot data within the repository. Instead of encrypting the entirerepository, AppAssure 5 lets you specify an encryption key during the protection of an agent in a repository which letsthe keys be re-used for different agents. Encryption does not impact performance, as each active encryption keycreates an encryption domain. Thus letting a single core support multitenancy by hosting multiple encryption domains.In a multi-tenant environment, data is partitioned and deduplicated within the encryption domains. Because you managethe encryption keys, loss of the volume cannot leak the keys. Key security concepts and considerations include:• Encryption is performed using 256-bit AES in Cipher Block Chaining (CBC) mode that is compliant with SHA-3.• Deduplication operates within an encryption domain to ensure privacy.• Encryption is performed without impact on performance.• You can add, remove, import, export, modify, and delete encryption keys that are configured on the AppAssure 5Core.• There is no limit to the number of encryption keys you can create on the Core.Adding An Encryption KeyTo add an encryption key:56
