Every good IT department knows that a business needs a plan for data backup. There’s simply too much that can go wrong to risk putting a customer or employee’s data on a single company hard drive. If the drive fails, the data’s gone, and data recovery costs are extremely high. However, different companies need different backup strategies. Otherwise, a method of backup may be inefficient or insufficient.
The odzyskiwanie danych companies use some proprietary tools for the purposes which are very costly indeed. So it is better to go for the recovery company rather than tempting to buy one.
Modern day hard drives store data via magnetic variations. If those read/write heads touch the platter, it means that part of the magnetically stored information is being physically wiped away. It will turn to fine dust and depending on how much of the platter gets wiped away, you can kiss any chance of retrieving your data good bye.
The first thing that you should do is not use your computer until an expert repair person can look at it. If you continue to use your computer in some of these situations, you could experience even greater data loss.
If the system finds that there is a damaged or faulty hard drive, DO NOT ATTEMPT to reconfigure the RAID even if the system prompts you to do so at any time. Use your own judgement when it comes to handling the system. Once platters are damaged, striping overwritten or changed completely, the chances of getting your data back are slim. Keeping that in mind, try not to reconfigure the system at all. Leave it as it is, and try to sort out the problem through a different route.
Incorrect permissions of ‘.Trash’ or ‘.Trashes’ folder can be the issue which may delete the file permanently without the user’s intervention. This can also cause problems, such as discussed above.
With any backup solution, be sure you are matching at the minimum your data file size. Ex: Your hard drive is 250 gigabytes. Don’t buy an external hard drive less than 250 gigabytes. For Flash drives, make sure the total amount of files you plan to put on it doesn’t exceed the allowed space. Above all, any data that is backed up is useless unless it is protected. This can be done by taking the backup off site away from the the original or invest in a fire safety box. The smaller boxes work well with tapes, dvd’s, cd’s, & flash drives. A larger firebox will be needed for external hard drives.
