Compression
MrBackup uses a dual layer compression procedure with non-compatible internal compression algorithms, increasing data security. With certain data types, compression ratios in excess of 94% may be achieved.
Encryption
MrBackup uses internally generated, restricted non-public 1024 bit SSH-2 RSA private certificates, with limited life cycles on a one-client only basis, increasing data security. These files are not suitable for installation as Public Key Security Object Files.
Additional user password encryption may also be used. This password is not retained, and if lost, the data may not be recoverable.
Upload
MrBackup requires the client to have broadband Internet available in order to upload each data set. Unlimited uploads are allowed. The most recent eight (8) uploads are uniquely identified and archived, allowing older data to be automatically removed from the storage server.
HMAC-MD5 file fingerprint
MrBackup makes use of the 128 bit MD5 algorithm, developed by Ron Rivest of the MIT Laboratory for Computer Science and RSA Data Security, Inc. The algorithm, with a reference implementation, was published as Internet RFC 1321 in April 1992, and was placed into the public domain. Hash-based message authentication codes or checksums such as MD5 fingerprints are not an “encryption technology” and should not be confused with data security applications. The purpose of the MD5 file fingerprint is to confirm accurate data upload. It is unlikely that any two non-identical files in the MrBackup environment will have the same MD5 hash.
Version Control
MrBackup guarantees the availability of at least eight (8) unique, complete data sets. Once uploaded, these data sets are date stamped and archived in chronological order to allow for easy identification of the required data set and shortest possible recovery time. In order to retain and make available any individual archived data set from the archive as a unique, stand alone data set, a non-incremental approach to data storage is used, with intentional non-deduplication and multiple retained redundant data sets. This guarantees multiple independent individual Point-in-Time recovery options.
Standard Storage Profile (1y;3m;8d) Most clients opt for the Standard Storage Profile, with a history of backups composed of
- most recent uploads (eight)
- most recent month end uploads (three)
- most recent financial year end (one)
maintaining at least twelve (12) guaranteed unique and recoverable backups at any given time.
Custom Storage Profiles (12y;8d) Custom Storage Profiles are also available, especially for systems that truncate data, where an actual month end backup needs to be retained for longer. Every month end backup can be retained for a year, while only eight other most recent anytime backups are kept. Custom means that storage profiles can be developed based on client’s needs, including PERMANENT storage options.
