You shouldn't care that they're top level, only which ones are the
right type.
Like this:
mount | awk '$5 ~ /^(xfs|ext2|ext3)$/ { print $1 }'
So in a script:
mountpoints=$( mount | awk '$5 ~ /^(xfs|ext2|ext3)$/ { print $1 }' )
for fs in $mount_points
do
... backup $fs, eg rsync -x $fs ...
done
Expand the list of filesystem types with the ones you actually use;
I tend to use xfs myself.
You may want to explicitly avoid removable drives if they mount in
a recognisably place. For example, I hand mount removable drives
as /mnt/whatever, so I would avoid mount points starting with /mnt/
to keep them from polluting my backup system.
I believe the recommended way to list filesystems (for many Fedoras) is
to use findmnt. This should be easy to use:
$ findmnt -l -o FSTYPE,TARGET | grep -E 'ext|ntfs|fat|xfs'
Hope this helps,

I think you meant `print $3'.
Yes. Brain off. Sorry.

I would run any backup/restore of the root filesystem only when booted from an external medium, to avoid problems with locks. What I do (and what would also work in your case) is: 1. Download sysresccd: http://www.sysresccd.org 2. Install the image on a memory stick: isohybrid sysresccd-image.iso cat sysresccd-image.iso /dev/sdX 3. Boot from it 4. Backup your partitions: rsync -avxHSAX /source/ /target To switch back to your system as it has been before a faulty update: rsync -avxHSAX --delete /target/ /source -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?

These days, there are quite a few special filesystems mounted on a running Linux system, but /proc and /sys are likely to be the only *top level* ones, plus /tmp may be on tmpfs. Type 'mount' and look at what you have on your system. -- Matthew Miller-- Fedora Project--mat...@fedoraproject.org -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
