Backup Solutions

Everyone should know that data loss can occur at any time. Whether through a virus, power surge, drive failure or accidental deletion, you will loose data at some time. The question not if, but when. How does your data get backed-up? Will it be safe if a disaster strikes? BTS can you find an implement a backup solution that fits your needs and budget.

There are several different types of data backup that you should be aware of.

 

  • Backup to tape – This is the most common method and provides high-capacity backups that can be move offsite for safety.
  • Disk to Disk backup – This is a very quick method of backup and recovery and is becoming cheaper as cost of storage goes down. 
  • Offsite backup – This method is relatively new and allows companies to backup data to a secure server offsite.

Tape backups provide complete control over your backups as well as provide a way to store data in a secure offsite location in case a disaster occurs at the main site.

Without moving data offsite, a disaster such as flooding, fire or act of God can destroy all remnants of your data.  With tape backups, there is a larger up front cost in purchasing a tape drive, tapes and software.  There will also be ongoing costs of drive maintenance, software upgrades and new backup tapes.
Tape drives that are too slow may run into the next day and tapes that are too small may require changing tapes in the middle of the night to complete.  This may require an upgrdae to a larger tape system. Tapes must be routinely checked to make sure they are still good and data is able to be restored.

Disk-to-Disk backups are fast and relatively cheap.  This type of backup can be used to make backups quickly, throughout the day, and provide almost instant restores for data.  As disk drives drop in price, this method becomes an attractive solution for rapid backups, and is often in addition to another method of backup.  The drawback is that it still requires the purchase of backup software, periodic software upgrades and does not provide for offsite storage without a costly site to site backup solution. Off-the-shelf drives designed for home backups usually do not provide the relaibility needed for businesses and will likely be lost along with the original data, in the case of a disaster, because they are not easily moved offsite.

Offsite backup uses special software to copy files from your servers and computers to a remote secure, third-party storage site.  This solution is usually billed on a monthly, quarterly or yearly rate based on the amount of storage you use.  The initial backup can take several days, but subsequent, periodic backups will take only minutes over the Internet because only changed data is backed up.  This has the added effect of allowing for multiple revisions of a file to be kept. 
You need to be aware that there are often two different levels of this type of service.  Personal backups are often offered as unlimited storage for a set price per month or year, but this type of service does not allow for backing up open files (such as files someone forgot to exit from) or database backups, and the professional services will often allow for database and open file backups.
While there are little to no up front costs, this will become a recurring cost and the backup speed will be dependent on your Internet connection.
