Note that systems which use GNU cp version 5.9 or later will have problems
52
with rsnapshot versions up to and including 1.2.3, if cmd_cp is enabled
53
(and points at the later gnu cp). GNU cp was changed in 2005 not to create
54
a destination directory if it has a trailing slash.
56
This problem was found with SuSE version 9.3 and Gentoo in 2005.
57
Users of these systems mostly opt to disable cmd_cp.
58
It is believed that rsnapshot version 1.2.4 will interoperate nicely
59
with gnu cp versions 5.9.x.

If you have rsync version 2.5.7 or later, you may want to enable the
50
link_dest parameter in the rsnapshot.conf file. This will allow you to handle
51
any type of file on any operating system.
53
If you do not have rsync 2.5.7 or newer, but you are running Linux, be sure
54
and enable the cmd_cp parameter in rsnapshot.conf.

These options are both off by default for maximum compatibility. However, if
57
you enable one of them you will be able to back up your entire system, not

When running rsnapshot on a system without either of these two options

specifically, FIFOs, sockets, block and character devices will not be

accomplish this in Perl (and if you know how, please let me know).

If you are running Linux but do not have the problem above, you should

enable the cmd_cp parameter in rsnapshot.conf (especially if you do not

have link_dest enabled).

Be advised that currently link_dest doesn't do well with unavailable hosts.
