Tape is THE product when it comes to Data archiving .

Tape is the ideal product for long-term data preservation. We are talking here about an accumulation of data that is not deleted due to policies and laws or is important as corporate assets.

  • Fujifilm is the leading manufacturer of tape media with a market share of 60%-70% depending on the respective LTO generation.
  • Tape technology has 60% of the market share in the field of data archiving
  • Every fourth file created is an archive file.
  • Every seventh stored file in private and professional environments is saved on tape.
  • A user who backs up 140 TB on a combination of hard disk (40 TB) and tape (100 TB) can reduce costs by 4 - 5 times compared to a user who backs up 100 TB purely on hard disk. It also saves 65% of energy costs.

One in seven files worldwide is stored on tape (Horison).

24% of the data stored worldwide is archive data (IDC).

97% of the 10,000 largest European companies use tape.

SMBs that use tape back up, on average, 100% of their data to tape and 20% to HDD.

Studies show that a total of 664 million tons of CO2 could be saved by switching to tape between 2019 and 2030.

Our Technical Service Centre lets you sleep soundly again.

As a leading tape manufacturer, Fujifilm has a European Technical Service Centre. The aim is
to offer you a technical diagnostic centre that works in two ways—
—on the one hand we offer preventive support and on the other, a diagnosis and repair service.


Have you ever had the problem that your system could not write the full capacity, but nobody could explain where the issue was?

 


One reason for this can be a drive head that is too old and worn so that it loses its magnetic properties.

When the head is worn out, it can no longer pick up the magnetic signals of the tapes correctly and it reads correctly written data as faulty. Since it is already checked during the writing process whether the data has been written correctly, the supposedly incorrect data is written again and again, checked, deemed incorrect and rewritten, so that the backup time is much longer than normal. In addition, a loss of capacity results due to the repeated writing of data.

One reason that a drive head wears out faster can be a rough belt surface. that removes material from the head as if it were being ground off. This happens especially with new tapes, as a new tape cartridge has a higher surface roughness than a tape that has been used repeatedly. For this reason, a drive head wears out faster than regularly used tapes. A smooth surface is therefore essential for stable recording and a longer life of the head.

A worn drive head can cause data to be written with an insufficiently high signal-to-noise ratio (SNR). The SNR provides information about the clarity of the signal sent from the tape surface to the drive head. It is then possible that the data can only be read by drives that have a head with better properties.


A second reason may be that the head is dirty so that it cannot be read properly.

When the head is worn out, it can no longer pick up the magnetic signals of the tapes correctly and it reads correctly written data as faulty. Since it is already checked during the writing process whether the data has been written correctly, the supposedly incorrect data is written again and again, checked, deemed incorrect and rewritten, so that the backup time is much longer than normal. In addition, a loss of capacity results due to the repeated writing of data.



Thirdly, incorrect software settings can lead to a misinterpretation of the capacity.

Besides the two mentioned above, there are other possible causes. For example, the user may have a problem interpreting the capacity of the system. This is typical when using data carriers of any kind. The system calculates with decimal capacity (used for recording media, hard disks) instead of binary capacity (used for hardware and software). Incorrect backup software settings in terms of the size of the data blocks can also lead to this. If we look at an LTO7 tape, it can be said that 6 TB decimal is close to 5.45 TB binary. If this is added to the data tape, it may result in only 5.56 TB being displayed. In one case brought to the Technical Service Centre, the cause was a misinterpretation of the LPOS (Longitudinal Position). This problem could be solved by updating the the LTO drive’s firmware.

Our solution.

No matter what the problem is, you can always send us the tape or the RFID chip from the tape for analysis. With special procedures, we can read the data on the chip, and thus also the error sources. Small mistakes can become huge problems and limit daily operations. Therefore, it is important to have a point of contact when problems arise. In the case of the first two problems, we explained to users exactly what they needed to tell the hardware manufacturers so that remedial action could be taken.
 

In the first example, the drives had to be replaced and in the second example, maintenance was sufficient. As the third case shows, however, it can also be due to a faulty setting in the software. We can also solve problems of all shapes and sizes.

This is tape.
