Re: [ADSM-L] Backup to LTO7 tapes

 Content preview:  We backup genomic data directly to LTO7 (100+ GB files are
    pretty ideal for it). I think the most important thing is that you set your
    TXNBYTELIMIT as high as possible (we do this via server-side client option
    set). You can also set the server option TXNGROUPMAX higher than the default
    of 4096 but this won't have any effect if your files are already bigger than
    TXNBYTELIMIT. [...]

Finally, if you have a mix of large and small files, make sure the small
files end up in a FILE or DISK pool before getting migrated to tape.
