Hello! I just installed my first system using XFS filesystem, and the xfsdump
utility seems interesting. I was following this guide about it, but it does not mention anything about the /media mount point: if I have a USB drive full of files mounted in /media/HDD1 and run
xfsdump -f /data/wholesystem.xfsdump /
will the files on the USB be backupped as well? and what about the /home directory?
It will not. Xfsdump only dumps the xfs partition, and any mountpoints are treated as empty folders (which they kind of are).
ok got it, so /home will be backupped and /media will not, correct? thank you very much!
Assuming that /home resides on the same filesystem, and is not a separate mountpoint, yes.
I read the man page, but I didn’t see the answer to your question in there.
I am assuming that it would only dump the root filesystem in your example. Other mounted filesystems like /home or /media, if they’re separate filesystems, probably aren’t included. You’d have to run a separate dump for each one.
Best option to find out is to try it and see what happens. No better way to learn than by doing.
