• Internet Explorer 5.5 and above
• Firefox 1.0 and above e
• Netscape 7.0 and above

• System State / Active Directory backups in DataSafe are treated like any other data backup. DataSafe 1-Click selection of preset backups now includes the system state / active directory allowing you to simply select it with 1-Click.

• DataSafe supports Exchange Server backups for Exchange Server 2000 with Service Pack 3 / Exchange Server 2003 / Exchange Server 2007
• You can now choose between the Basic / Advanced Exchange Server Plug-in in DataSafe. The Basic plug-in for Exchange Server backup is provided with your DataSafe installation and uses the NTBackup utility to dump Storage Group data. The Advanced (Plugin) Exchange Server backup uses the ESE ( Extensible Storage Engine ) API to backup Storage Groups and Mail Stores.
• Incremental features in the Advanced plug-in include:
• Optimal use of dump files for local storage: the dump file is compressed and automatically purged after use (In Basic plug-in, the dump file will be maintained  locally in the client machine for further differential log backups)
• Support for Storage Group level and Mail Store Level backup
• Straight through Restore of Exchange Server backup (as opposed to a 2 step process in Basic plug-in)
• Comprehensive Backup & Restore report of Exchange Server backup is available
• Detailed Exchange Server Backup & Restore email reports available

• DataSafe supports SQL Server backups for SQL Server 2000 and all higher versions.
  You can choose between  Basic & an Advanced SQL Server Plug-in. The Basic Plugin uses the OSQL utility to dump the database(s) and thereafter uploads the locally dumped file to the backup server. The Advanced SQL Server plugin uses the VDI (Virtual Desktop Infrastructure) API to backup database(s) before uploading them to the backup server.
• Incremental features in the Advanced plug-in include:
• Optimal use of dump files for local storage: the dump file is compressed and automatically purged after use.
• Straight through Restore of SQL Server backup (as opposed to a 2 step process in Basic plug-in)
• Comprehensive Backup & Restore report of SQL Server backup is available
• Detailed SQL Server Backup & Restore email reports available

• The ability to intelligently handle incremental data is a key component of any backup solution! Especially since this has huge implications on performance and infrastructural and operational costs- bandwidth and storage costs being the most crucial of these!
• Our Intelli-Delta technology, based on the powerful & proven RSYNC algorithm, ensures that after the first 'seed' backup, only 'optimized byte level' changes in individual files & folders are backed up thereafter.
• Most backup software implement incremental backups in fixed block sizes (eg. 4K blocks). In effect, they divide files into blocks of a pre decided size, examine CHECKSUMS of blocks that are detected to have changed and retransmit the changed blocks!.
• DataSafe does not implement pre decided block sizes as this is often sub-optimal. For a small file, the block size may be too large and hence translate to a larger amount of data being sent than what's required. For very large files, a small block size translates to performance degradation. DataSafe decides on individually optimal block sizes for every single file after taking into account the original file size. This ensures that for each file, changes are examined at an 'optimized byte level'.

DataSafe uses the following, to ensure the security of data:

1. Authenticated connection between client and the backup server. During the client-server connection initialization, the client and the backup server generate random private/public key pairs and based on this random key pair the authentication takes place with the client password (hashed and encrypted with the private key). The private keys are never sent out from the client or the server.
2. The backup data encryption password is hashed before sending it to the backup server. Also, DataSafe uses its own protocol (not HTTP) over raw TCP sockets over SSL for communication between the client and the backup server. The passwords are never transmitted in clear text. Even if the connection between the client and server is through raw TCP sockets (and not using SSL over TCP) the passwords can never be read as they are all hashed and sent.
3. DataSafe design the backup server never requires the encryption password at all. The hashed encryption password is sent just for the backup server to verify that the encryption password has not changed across different schedules for the backup. If it did the backup server will not accept the backup as encryption passwords cannot change across schedules.
4. Therefore, even if the data is sniffed while in transition from the client to the backup server, the encryption password cannot be captured. Without the encryption password, the encrypted (BlowFish encrypted, up to 448 bit ) backup data cannot be decrypted. And same is the case with the authentication password used for connection between the client and the backup server.

While configuring the backups using DataSafe to eliminate security concerns you should do the following:

1. Enable SSL in the client to ensure all communications between the client and the backup server are secure.
2. Choose a good backup data encryption password.
