You’ve heard it thousands of times — backup your data. A good data backup strategy is to have two copies of your data – one local (it resides in your office or place of business) and one offsite (you pay an online data company to store it remotely on their secure servers).
Online backup is now a must have for all computer users, as we now live in a digital age where our whole digital life is store online. Our files, photos, music, video, financials and more are all stored on our computer hard drives. But what happens if your hard drives crash? All hard drives will fail eventually and they usually happen at random when you least expect them. We no longer have CD collections, or DVD racks with our films, or photo albums of our photos, they are all stored on our hard drives. Theft, Fire, Accidental deletion, hardware failure, all these can contribute to lost files. Files which are no longer just binary text, these files are irreplaceable memories which money cannot buy back.
Online Backup for Small Business
Tips For Buying Online Backup Services:
Below are some of the main factors to consider when selecting an online data backup providers:
1. The Kind of Backup User You Are:
A service designed for home users or small businesses is quite different than one designed for the enterprise. The latter requires complex features such as ability to backup operating system files, live database, historical backup, and extremely tight encryption, while the former would be happy with a relatively low priced service that provides common features such as scheduled backup, web access, ability to send files by CD/DVD, and share files with others.
2. In general, online backup users should ask the following questions:
3. Security
To ensure that your data is secure while it is being transferred from your computer to the provider’s data center, most providers offer the option of encryption and password protection. In this way, only someone with your password can access your data.
In most cases a 128-bit encryption is sufficient. For some businesses that want absolute privacy, security might require a much stronger encryption. Although not very common, some providers offer a 448-bit encryption. In addition, data has to remain secure once it reaches the destination server, which means providers have to have proper policies to ensure employees do not access client data for non-authorized reasons. Most providers take the issue of security very seriously, as it is one of the reasons why computer users are hesitant to backup online.
4. Speed, Reliability and Uptime
As backups are usually a last resort way of recovering data after a disaster or system failure, backup providers don’t have much of a margin of error. The data has to be there when needed. No amount of explanation on why the data is not available will calm a user that just lost an entire computer hard drive and is trying to restore from a backup.
To ensure the provider has taken sufficient steps to keep service reliable, you should ask the following questions:
Does the backup provider have a “backup†copy of all clients’ data somewhere on a secondary data center, away from the primary?
Is the backup center equipped with uninterruptible power supply, backup generator and is it located in a safe and secure location?
What is the uptime for the data center?
How many clicks does it take before the actual backup is started?
How fast is the data center?
How much CPU or disk resources does it chew up when the backup is running?
Where is the geographic location of the data center?
Is the backup continues?
How many years has this Online Backup Service Provider been in business or does the company have solid financial resources?
How fast can files be restored?
Who are the clients of this company?
How many paying customers does the company have?
5. Quality and Accessibility of Technical Support
Does the company have a toll free number?
Is technical support available 24/7?
Does this company reveal its email address in their site or does it force me to fill in a time consuming form?
Is there an emergency user support?
Does the company have a physical address listed in their site?
What is the turn around time for email queries?
Does the company have an international presence?
Does the company publish a customer support satisfaction survey stats?
What is the wait time for phone support?
6. Cost
How much does this Online Backup Service Provider charge per GB per month?
Is there a set-up fee?
Is the cost per account or per PC?
How often and how much data are allowed for backup per day or per month?
Is there a no obligation free trial period before I sign up?
Can I cancel at any time or am I tied in for a minimum period?
What is the cost for exceeding the allowable traffic and storage quota?
Is there extra cost for telephone technical support?

2. Fixing Seagate BSY or CC errors aka BUSY (I recommend some practice before trying this):
Note: All commands are case sensitive !
Explanation: The problem with the drive is that the drive is stuck/halt in a BUSY state. This basically locks up the SATA port, causing the BIOS problem (cannot detect the drive at POST). In the terminal, you will see this sort of error (LED: 000000CC FAddr: 0024A051). Once you see this in the terminal, the terminal session to the drive is completely blocked and will not accept any more commands. In order to circumvent this, we’ll need to disconnect the PCB (circuit board) from the hard drive case so that the LED: 000000CC FAddr: 0024A051 command cannot be sent from the firmware of the terminal session.
After you have connected the power to the circuit board, press CTRL+Z in your HyperTerminal session. You should now see a prompt like this:
F3 T>
If you do not see this prompt, check your RS-232 connections to the drive. (you may have the TX and RX flipped).
Now we’ll need to access the Level 2, type:
F3 T>/2 (enter) F3 2>
And type (to spind down the motor):
F3 2>Z (enter) Spin Down Complete Elapsed Time 0.147 msecs (the time will vary here) F3 2>
Now the tricky part. Pratice a lot without any power before even trying this. You need to make sure that the screws don’t touch the PCB board where they aren’t suppose to or you will fry your PCB board. If you have been practicing and the power is not connected, start at STEP ONE.
With the POWER CONNECTED to the PCB board, as well as your TX/RX terminal wires, mount the board back on the HDA case. You must have the power connected when you do this.
Now type (to start the motor):
F3 2>U (enter)
You should get something like this:
Spin Up Complete
Elapsed Time 7.093 secs
F3 2>
Then go to Level 1 (by typing /1):
F3 2>/1 (enter)
Now lets do a S.M.A.R.T. erase (create S.M.A.R.T. sector):
F3 1>N1 (enter)
————————————————————————————-
G-List step is optional:
Skip G-List step first, if after proceeding the whole BSY fix and the drive still remains under BSY error, then you’ll need to repeat BSY process with G-List command below.
G-List Erase (Fix Defect List):
F3 1>/T (enter) F3 T>i4,1,22 (enter)
For reference:
Level T ‘i’: Rev 0001.0000, Overlay, InitDefectList, i[DefectListSelect],[SaveListOpt],[ValidKey]
————————————————————————————-
Power OFF/ON the drive (very important!)
Wait 10 seconds and now Power ON your drive.
Press CTRL+Z on terminal and type:
Partition regeneration:
F3 T>m0,2,2,,,,,22 (enter)
For reference:
Level T ‘m’: Rev 0001.0000, Flash, FormatPartition, m[Partition],[FormatOpts],[DefectListOpts],[MaxWrRetryCnt],[MaxRdRetryCnt],[MaxEccTLevel],[MaxCertif
yTrkRewrites],[ValidKey]
You should get something like (in around 15~30 seconds):
Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8 User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, ErrCode 00000080, Elapsed Time 0 mins 05 secs User Partition Format Successful - Elapsed Time 0 mins 05 secs
If you didn’t get the msg above, then you skipped something important, and turning off your drive now will render an unreadable drive, so be careful.
ONLY after the message like above you can turn off everything.
