    Cannot backup /dev in RHAS 4.0(AMD 64bit)


    /dev was not backed up.

    On Linux, there are three ways to find the list of mounted filesystems.

    a) From file /etc/mtab
    b) From file /proc/mounts
    c) From the command df.

    The mounted filesystem /dev was not listed in /etc/mtab, but was available in /proc/mounts.
    The Linux documentation says that /proc/mounts is a more reliable place for information on mounted
    filesystems, but our backup application is designed to use the /etc/mtab.

    [/b] what is the the differences in /dev listings in /etc/mtab
    and /proc/mounts?[/b]

    Why would you backup /dev? It's useless, same for /proc and temporary dirs (/tmp and /var/tmp).

    using a Backup tool I was taking Host backup, while persuing it I face problems only with /dev directory.

    Maybe you can configure it to not backup those?
