backing up /proc filesystem ?

Jean-Yves Picard — Tue, 11 Jul 2006 09:43:46 GMT

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 ...

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

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.
