LTO-8 Library and Linear Tape File System

Hi, was wondering if the group here can help guide me in the right direction:

1) I have 75-100 TB’s of data than I need to keep online or near-line.

2) These data sets do not change and seldom deleted

3) Currently, we are storing them in a large RAID 6 array, and have a duplicate array for backup

4) My worry is both array’s will fail leading to data loss

Is there a way to access a LTO-8 library like it’s a hard drive? We don’t need super high speed access since we can copy the data sets as we use them to local harddrives.

I don’t know too much about LTO tape libraries, but was thinking this will be a good use of tape storage.

Thanks!

For 75–100TB of data that rarely changes and only needs near-line access, moving from dual RAID 6 arrays to an LTO-8 tape setup is a practical and safer long-term option. LTO-8 provides 12TB native capacity per cartridge, so the entire archive would fit on fewer than a dozen tapes, with the option to create a second set for offsite storage. Using Linear Tape File System, each tape can be mounted like a large removable drive, letting you browse folders and copy datasets to local storage when needed. Although tape is slower than disk for random access, it works well for large, infrequently accessed archives. Unlike RAID, offline tape copies are not exposed to ransomware, power surges, controller failures, or simultaneous array loss, making them a more reliable choice for long-term retention of static data.
