The most reliable storage medium
Good day dear Habrchane!
In a long time, at one time, I thought that having a backup on an additional hard disk or on a network folder or somewhere else (considering the raid there) will provide 100% the ability to recover lost data. As I was wrong ... ... It was self-confidence that was to blame, I thought that rewriting a part into blanks and putting everything in a dark-dark cabinet would be fine.
Several years have passed and tax information was required 3-4 years ago (despite the fact that the financial information retention period is 5 years, and personal data is 75 YEARS !!!). Tell about the fact that at the very last moment it turned out that the raid broke, the discs were rewritten, the discs are not readable, I will not - there will be too many sounds “3.14159 ....” that I heard from the manual.
But I came to the conclusion that backup should be approached with extreme caution, starting from the backup regulations and ending with the choice of storage media providing reliable, in the sense of being able to recover information after a long period of time in its original state.
Many manufacturers claim that the lifetime of information on their products (cd / dvd / hdd) can be tens of years, although in practice this is not the case.

My choice, of course, was on tape carriers, they are more durable both in terms of storage conditions and in terms of this storage. Now I use:
Having backup data on hard drives or cd / dvd drives is not an option. Normal backups (today) should be implemented on tape libraries with magnetic tapes. (about the fact that the sensible backup is done multi-level - first on the HDD and then on the tape for the availability of operational backup I will not stop)
I will dwell on one more criterion - no need to chase cheap!
PS In general, if something is very, well, very valuable (root password), then knocking it out on a stone can be obtained ...
They say this "data" 27000 years)
Although the stone is good, but not convenient :-) so that for the time being, use tapes for safe storage)
It remains to ask you whether you use tape libraries?
PPS: Do not throw away (put a comma yourself)
Thank.
