Hi all,

Is there someone here using LTO tapes as a backup solution on FreeBSD systems ? If so, which format is recommended ? No problem on making tar tapes on FreeBSD like on Linux systems ?
What about LTFS, anybody have some information on implementing Linear Tape File System on FreeBSD ?


Thanks in advance..

I don't use LTO, but tar works on tapes - it has always worked.

I use tar(1) with LTO3 drive/tapes on FreeBSD, works as desired. You can try bigger tar(1) --block-size option such as 8192, for better transfer rate.

As described be, FreeBSD (as usual) is not one of the supported platforms:

Maybe the FreeBSD Foundation could do something about it.

Hello Vermaden, thanks for your reply.
Good to know that tar works fine and I asked about the LTFS just to be sure. I really would like to get this working on FreeBSD systems. This is really the default future of LTO tapes.

Thank you!

The LTFS is only useful on LTO5 and LTO6 (and possibly later models) as LTO4 and earlier specifications does not support partitioning, which is required by LTFS.

It's an older thread but it seems that ltfs is still unsuported by FreeBSD. At least I did not find any information regarding LTFS under FreeBSD. Is this correct?

Thanks a lot!

LTFS is unsupported on FreeBSD. Linux/macOS/Windows only. Not even IBM AIX is supported.

Thanks for your quick reply. I assume you mean LTFS is unsupported in your first sentence :).
