Solving the backup & recovery puzzle
As a general rule of thumb, there are two pieces in the puzzle of creating a comprehensive backup and recovery scenario for any business:
Data archival backup: long term data storage spanning months or years.
Fast system recovery: recovering a server due to hardware fault or some kind of catastrophe
Data archival backup gives you the ability to restore your files and data from the past – sometimes from months or years in the past. For example, if you go to retrieve accounting data from 2007, but discover that the folder has been accidentally deleted (and you have no idea when), you’ll most likely need to go to a backup from 2007 to find the documents.
Many countries now have laws requiring businesses to keep records for 5 years, or sometimes even as long as 7 years, so data archival backup has a role to play in helping meet legal compliance requirements for every business, large or small. It’s important to use well known and accessible backup file formats, so you can be sure that you will always be able to restore your data, well into the future.
System recovery involves rebuilding a system from scratch. For example, if your business is hit by a natural disaster and your server is destroyed, or if it’s stolen, or even if your hard drives crash beyond recovery – you’ll need to rebuild your entire system. Often you’ll be restoring data to new hardware, so Hardware Independent Restore (HIR) will be required. And because you’ll be using new hardware with no existing operating system, it’ll be a Bare Metal Restore. Most of the time, you’ll want to recover your system from the most recent backup, so you can get running quickly and with minimal data loss.
The causes of data loss
According to recent research (available at http://www.acspc.net/dataloss.php), 48% of data loss cases are from human error, software corruption and viruses. These cases may not require a system to be entirely rebuilt, but instead require the restoration of data that may be years old. In this case, having historical copies of your data (known as data archival backups) is important.In addition, 52% of data loss is caused by a hardware failure, hardware destruction or theft. In these cases, it is likely that the entire system will need to be rebuilt.
Features available with local backups
Windows 2008, Windows 7 and Vista
Backup volumes, System State and VSS aware apps for fast disaster recovery. Hardware independent restore (HIR) is easy using a WinRE boot disk. BackupAssist provides extended hardware support, media rotation, monitoring and reporting for a complete solution.
