Bank of Memories

Many people think about how to save data for years to come, and those who do not, may simply not know that a CD with photos from the wedding, a video from a children’s matinee or other family and work information is more likely to not be read in 5 years -10. I’m thinking. How can you store this data?

General principles of information storage, prolonging the period of her life

There are the most general principles that apply to any type of information, be they photographs, text or files and that can increase the probability of successful access to it in the future, among them:

The larger the number of copies, the more likely that the data will survive longer: a book printed in million copies, a photo printed in several copies for each relative and stored digitally on different drives, is likely to be stored and available for a long time.
You should avoid non-standard ways of storing (in any case, as the only way), exotic and proprietary formats, languages ​​(for example, for documents it is better to use ODF and TXT, not DOCX and DOC).

Keep the information in uncompressed formats and in an unencrypted format — otherwise, even a minor corruption of data integrity can make all information inaccessible. For example, if you need to save media files for a long time, then WAV will be better for sound, uncompressed RAW, TIFF and BMP for photos, for video — frames without compression, DV, although this is not entirely possible in everyday life, considering the video volumes in these formats.

Regular checking of the integrity and availability of data, re-saving them using new emerging methods and devices.

The most common ways of storing various kinds of information for today are hard drives, flash drives (SSDs, USB flash drives, memory cards), optical disks (CD, DVD, Blu-ray) and not related to storage devices, but also serving the same purpose Store (Dropbox, Yandex Drive, Google Drive, OneDrive).

Which of the following methods is a reliable way to save data? I propose to consider them in order (I’m talking only about household methods: streamers, for example, I will not take into account):

Hard disks — traditional HDDs are most often used to store a wide variety of data. In normal use, their average service life is 3–10 years (this difference is due to both external factors and device quality). In this case: if you write down information on the hard disk, disconnect it from the computer and put it in the desk drawer, then the data can be counted without errors for approximately the same period of time. The security of data on the hard disk depends largely on external influences: any, not even strong shocks and shakes, to a lesser extent — magnetic fields, can cause premature failure of the drive.

USB Flash, SSD — the service life of Flash drives on average about 5 years. In this case, conventional flash drives very often fail much before this time: one static discharge is sufficient when connected to a computer, so that the data become inaccessible. If you record important information and then turn off the SSD or flash drive for storage, the data availability period is about 7–8 years. USB Flash Drives

CD, DVD, Blu-Ray — of all the listed, optical discs provide the longest storage period of data that can exceed 100 years, but this type of drives is associated with the greatest number of nuances (for example, the DVD recorded by you, most likely will live only a couple of years)

Cloud storage — the term of data storage in the clouds Google, Microsoft, Yandex and others is unknown. Most likely, they will be stored for a long time and while it is commercially justified for the company providing the service. According to the license agreements (I read two, for the most popular repositories), these companies do not bear responsibility for the loss of data. Do not forget about the possibility of losing your account due to the actions of intruders and other unforeseen circumstances (and their list is really wide).

So, the most reliable and durable household drive at this point in time is an optical compact disc (which I will write in detail below). However, the cheapest and most convenient are hard drives and cloud storage. Do not neglect any of these methods, because their sharing increases the safety of important data.

But all these drives have many disadvantages and drawbacks!

Bank of Memories is the world’s first service to create, store and send emotional content to the future. Integrated genealogical tree function based on Blockchain technology.

What are the cool features you get:

Emotional messages

The most “charged” content that will be saved from the moment it was created and delivered to the specified user or sender of the message unexpectedly or with a notification at a certain time is what the user does not want or does not want ready for transmission or showing at the moment.

Family tree

A genealogical tree is a profile that identifies relatives, accumulates information about a person and is a personal cell, stores information about the genus that is available only to members of the genus.

Digital monument

A digital monument is a special section of the Genealogical tree, in which the confirmed information about a person accumulates, which will become public after the death of a person in the form of a QR code. Emergency access to the cell is realized using a public key.
