Hello all!
Trying to improve the backup speed with BPC and looked into setting
noatime
in fstab.
But this article states some backup programs may bork if noatime is set.

What will BPC in particular do if noatime is set?
exactly what it's supposed to do. noatime or at least relatime (or
perhaps recently lazytime) is the recommended setting:

I think it depends on whether you are applying this setting change on
the BPC server, and specifically the BPC pool drive, or if you are
applying it to the clients and/or root FS of the BPC server.
If you have a separate filesystem for the BPC pool, then using this
setting on that filesystem will not have any adverse impact, but will
likely reduce overhead. Changing this setting elsewhere will have the
documented impacts (and you would need to assess the results of those
impacts based on your own personal requirements (or provide a lot more
information for anyone else to comment on).

Adam
