	# Old article

	Hello, it turned out that this article is obsolete. The security used
	in is not
	safe at all so the goal of this backup system isn't achievable, thus it
	should
	not be used and I need another backup system.

	One of the most important feature of dump for me was to keep track of
	the inodes
	numbers. A solution is to save the list of the inodes numbers and their
	path in
	a file before doing a backup. This can be achieved with the following
	command.

	$ doas ncheck -f "\I \P\n" /var

	If you need a backup tool, I would recommend the following:

	# Duplicity

	It supports remote backend like ftp/sftp which is quite convenient as
	you don't
	need any configuration on this other side. It supports compression and
	incremental backup. I think it has some GUI tools available.

	# Restic

	It supports remote backend like cloud storage provider or sftp, it
	doesn't
	require any special tool on the remote side. It supports deduplication
	of the
	files and is able to manage multiples hosts in the same repository,
	this
	mean that if you backup multiple computers, the deduplication will work
	across
	them. This is the only backup software I know allowing this (I do not
	count
	backuppc which I find really unusable).

	# Borg

	It supports remote backend like ssh only if borg is installed on the
	other side.
	It supports compression and deduplication but it is not possible to
	save
	multiples hosts inside the same repository without doing a lot of hacks
	(which I
	won't recommend).
