| A LAN-based backup solution best fits a business or department that runs continual business processes and has several servers and workstations connected to a LAN that need to be backed up. If your business has some or all of these characteristics you may benefit from a LAN solution: |
|
|
• |
Operates a continuous, business-critical operation |
|
|
• |
Has unpredictable data growth |
|
|
• |
Requires hourly or daily backup |
|
|
• |
Has more than 5 networked servers |
|
|
• |
Supports multiple operating systems |
|
|
• |
Has already deployed a backup system |
|
|
• |
Is looking for a scalable, cost-effective solution |
|
|
• |
Needs to automate the backup process |
|
| In a LAN-based backup scenario, the backup management server can be connected to either the main LAN or a dedicated backup LAN. A dedicated backup LAN is recommended in situations where performance degradation in the main LAN because of backup volume is not acceptable. On a dedicated backup LAN, disk agents placed on servers and workstations push data over the LAN to the backup server, which then writes the data to tape or to some kind of disk array, such as disk-to-disk (D2D) backup systems. |
|
| A LAN-based backup solution is perfect if you want to automate your backup process and schedule backups on certain servers at certain times without manual intervention. For a smaller network, you could use an autoloader containing a single tape drive. On a larger network with a greater capacity requirement, you might select a tape library. Compared with standalone tape drives, these LAN-connected drives bring significant resource savings and reliability improvements to the DAS backup approach. |
|
| Capacity and performance planning are the keys to selecting the appropriate LAN-based backup device. The first step is to calculate the daily backup volume for each server and workstation. When you consider performance, keep in mind that a dedicated gigabit backup LAN will transfer data at about 80 MB/second as long as the media server has sufficient processing power to support the transfer. |
|
Considerations |
|
|
| As you consider LAN-based backup as a solution for your business, keep the following in mind: |
|
|
|
• |
A LAN-based data protection solution is limited to a maximum theoretical storage rate of 3600 GB/hr based on a gigabit Ethernet LAN But on a practical level, it's unlikely that your organization will achieve anything like that rate based on protocol overhead |
|
|
• |
A dedicated backup LAN will give you the best overall performance by segregating the user traffic and the backup traffic on to two separate paths. Because you're not mixing user traffic with backup traffic, you maximize performance for both users and backup |
|
|
• |
If you require a higher capacity and/or faster backup, a tape library with multiple drives (learn more about tape libraries), or a backup server with multiple Disk-to-disk (D2D) systems attached (learn more about D2D backup storage options) may be your best option
