We used TSM on our lustre filesystem for a while and it worked well
backups took about 3 days (the filesystem was 167TB but we weren't
trying to back it all up).  Prior to that we were trying to use BRU.
The runs took weeks, frequently failed and we had performance issues.
We suspect that BRU, being originally MAC  software, was attempting to
backup extended attributes (which we didn't really need) and
overstressing the MDS.
