After an initial install of a RHEL client I found everything when haywire when /proc was included in the backup. I guess the same would apply for /sys. How are these normally excluded? I'm thinking I made a mistake in configuring the client somewhere.
/proc and /sys on RHEL are extensive directory trees of files which can be read (about 7k entries under /proc). They are all size 0 but when you cat them there's info there from the kernel. I would have thought Networker would know by default not to try to back them up but it was. One of my LTO-5 tapes it was putting /proc on showed a capacity of 31TB used. Something weird was happening.
So I added to the Unix Standard Directives skip proc and skip sys.
the savefs probe would the one to verify with. It should automatically exclude. The expansion/client config wizard show everything regardless of whether it will be backed up or not.
savefs/save will automatically exclude /proc and /sys when saveset ALL is specified in the client resource. If you've explicitly referenced /proc and /sys in the savset then they will be backed up.
With save set All, no data under /proc and /sys will be captured. You can verify that with mminfo. Both filesystems are specific (proc and sysfs) and as such are not part of regular backups.

/proc is not an actual file or directory it is just a place that holds info on what is currently running
