backing up /proc filesystem ?

Hello,

I am writing procedure to backup restore linux hosts.

is there a point of backing up /proc filesystem ?

this filesystems looks to me as a view (in database acceptation of term), hence the only way you can have same /proc on both source host and target host is to (try to) rebuild the target exactly the same way as source host.
same size for vg, lvs etc ...

Re: backing up /proc filesystem ?

You don't have to backup the /proc file system, it's a virtual file system. The proc file system is populated at startup "on the fly". You only need to ensure that the /proc mount point exists.

Hi Jean,

/proc is a VFS. You can find more information about /proc here: http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/ch-proc.html

Re: backing up /proc filesystem ?

there is no use in backup /proc

settings in procs that are configured at boot time are included in the /etc directory so just be sure to have that included in your system backups.
