Step 9. Compression and Encryption Options

Specify compression and encryption options for the backup plan.

Backup for Windows allows you to compress your backup contents to decrease the space required to store the backup and the uploading time to the target backup storage.

In addition, you can protect your backup by encrypting its contents, file names, or both. TrueSecure Backup supports AES encryption with key sizes of 128, 192 and 256 bits.

The more the key size, the stronger the encryption (with more time required for processing your backup).

If you chose to save your backup plan configuration to the destination storage, this configuration file will not store the encryption password for security reasons and you need to save this password elsewhere to be able to restore the backup's contents afterward.

Note that if you change any of the encryption settings (algorithm or password), you will be prompted to select if you want to backup up the whole dataset on the next backup plan run with updated encryption settings or apply the updated encryption settings only to new files that would appear in the backup source at the moment of the backup plan execution

Specifying Amazon S3 Encryption Settings

If you selected Amazon S3 as destination storage for your backup, the Backup Wizard provides an extended version of this page enabling you to specify the encryption options for protecting the data stored on Amazon cloud servers as well.

The following additional settings are available when using Amazon S3 for storing your backup:

• Use Server-Side Encryption Enables encryption of your backup on the side of the Amazon cloud server.

Selecting the S3 Storage Class

If you selected Amazon S3 as a destination storage for your backup, you can make the backup service use the following storage classes:

• Standard
• Intelligent-Tiering
• Standard-IA
• One Zone-IA
• Glacier Instant Retrieval
• Glacier Deep Archive

Using Microsoft Azure Blob Storage

If you selected Microsoft Azure as destination storage for your backup, the Backup Wizard provides an extended version of this page enabling you to choose Azure Blob Storage.

You can choose among the following options:

• Archive Blob Storage This is a low-cost storage option for infrequently accessed data.

  As opposed to hot and cool storage tiers, fetching data from archive storage takes up to several hours.

• Cool Blob Storage Cool storage tier has lower storage costs and higher access costs compared to hot storage. This tier is intended for data that will remain in the cool tier for at least 30 days.

This feature is only supported for General Purpose v2 Azure accounts. If you are using another kind of account, you need to upgrade your account to be able to use this feature.

Please be informed about the additional charges and increased blob access rates resulting from upgrading your Azure account.
