“I lost all my documents!” How many times have you heard this phrase and how many times you have had the fear of pronouncing yourselves? So today, in our section of “scientific entertainment” we want to offer you a small guide on how to avoid or overcome this inconvenience!
Without going into too much detail, for which we advise you to ask to a technical expert, let’s start by explaining that there are different “ways” in which the data is saved on a hard disk and the disk space is divided to avoid writing errors and the famous “corrupted files”. But no one of these systems, even the most advanced, it’s 100% safe.
How to do so?
You may have heard it so many times, but the safest solution is … backup! The backup is nothing more than saving (in automatic way or not) a copy of all data, files, images, contained in your computer (but also in your smartphone). The backup can be done on a physical disk, such as an external hard drive, connected to your computer via the USB port or via Wi-Fi, or it can be online, hosted on clouds of web space where data are stored.
Both Microsoft and Apple have integrated into their operating systems the possibility to make a backup of the data on their respective platforms: OneDrive and iCloud, and make accessible these files even from another computer, through name and password.
Normally, the space that is offered for free is limited. But, if you are passionate about photography or the amount of documents you need is much, maybe there won’t be enough space, not to mention that the data transfer can sometimes be… very slow! In this case, perhaps the solution that’s right for you is an external drive.
Are you particularly forgetful?
We advise you to automate the process, using the appropriate application, such as Time Machine for Apple: when is up to you (once an hour, a day or a week), the data on your computer will be automatically copied to the hard disk outside and even you can recover a document that you accidentally thrown in the trash a few days before.
These devices are capable of operating even over Wi-Fi: so you will not even need to connect to the USB port. As soon as your computer is turned on within range of the network, your data will be automatically copied to safety.
Are you particularly apprehensive?
There is yet another solution for you!
Sometimes, there is a need to free up space on your computer, and then over to the backup, also serves as external storage. But who does the backup of backup? To avoid losing the data of the hard disk backup, you could install at least two disks configured in RAID-1 mode.
This configuration allows you to mirror the data saved in the hard drive in another ancillary units: the same information is also stored on another hard drive in parallel, minimizing the risk of data loss (if it becomes damaged unit, the other will remain functional).
So, you just have to find the solution that best suits your needs!
