EVault: How It Works

EVault is a Block Level, disk-to-disk data backup and recovery technology that employs WAN-optimized data transfers, end-to-end encryption, data reduction (source-side and back-end), and single-pass restores. It minimizes bandwidth usage, backup windows, and storage needs; ensures security, privacy, and compliance; and enables reliable point-and-click restores.

Initial Seed: First Full Backup

For large initial seeds, we will connect both Vaults on your LAN and complete the first backup process; when the backup is complete, we will ship the DR Vault to an offsite DR Centre.

• Initial seed compresses data by as much as 50 percent.  You can realistically expect up to 75% reduction on SQL, Oracle and Exchange.
• Back-end deduplication further reduces the footprint by as much as 20 percent
• Subsequent backups typically add only two percent new data

Delta Backups and WAN Optimization Technologies

After the initial seed, EVault finds and transmits only NEW and CHANGED data blocks, then dynamically builds virtual “synthetic full” backups. These delta backups work with adaptive compression, bandwidth throttling, and other WAN optimization technologies.

• Quick File Scan—Patented process rapidly scans files on every protected system or server to identify new or changed blocks.
• Adaptive Compression—Shrinks transmitted data blocks by 40 – 90 percent, using the best compression algorithm based on available CPU and network bandwidth.
• Dynamic Bandwidth Throttling—Controls bandwidth available for backup jobs, useful for frequent backups of critical data or for use in limited-bandwidth environments.
• Enhanced CPU Utilization—Automatically splits backup jobs across multiple CPUs, freeing source-system processing power for other tasks.
• Self Healing—A corrupted or missing delta index file doesn't stop EVault from identifying only new or changed blocks.

End-to-End Encryption

EVault encryption protects backup data inside the firewall; as it travels over the wire—the cloud connection is itself encrypted; and data in storage.

There are no “back door” decryption keys; only your organization’s key holder can supply the correct code.

• Front-End Encryption—Prior to leaving the backup server, data is encrypted using the National Institute of Standards and Technology (NIST) 128-bit or 256-bit Advanced Encryption Standard (AES).
• Over the Wire Encryption—The backup and restore activity is encrypted, ensuring the security of transmitted data even over the Internet.
• At-Rest Encryption—Data remains encrypted while in Covenco’s secure data centres at Langley and Banbury.

Efficient and Reliable Back-End Storage

Before storing your backup data, EVault identifies matching blocks across all files and eliminates duplicates. This back-end deduplication does not impact the backup window or performance; it can, however, reclaim 20 percent more storage space. EVault also automatically removes expired data blocks per your organization's retention policies.

Single-Pass Restores

EVault backup data is instantly recoverable via a simple point-and-click, one-step restore process. How is that possible? Because EVault dynamically builds virtual “synthetic full” backups dynamically—as each backup job arrives at the Vault—and continually ensures the integrity of backup data sets. Users can even restore their own data using the EVault Web Central Control management console.
