| As is [[http://sdf.lonestar.org/index.cgi?faq?MISC?01| clearly outlined in the FAQ]], SDF backups up system files only. SDF does NOT maintain backups of userspace. If there is something stored in your home directory that is important to you then you need to take on the responsibility of protecting it. Paragraph two of the [[http://sdf.lonestar.org/index.cgi?abuse/aup|SDF AUP]] also clearly outlines the fact that taking care of your files is your responsibility. | As is [[http://sdf.org/index.cgi?faq?MISC?01| clearly outlined in the FAQ]], SDF backups up system files only.

| What you will need to perform a mirror of your home directory on SDF to another location is a computer with ssh and rsync installed and enough space to store your SDF files. The instructions below are being run on an x86 running Linux, but should be suitable for Mac OS/X and Windows running cygwin. Please read the ssh and rsync documentation on those platforms for any differences. | What you will need to perform a mirror of your home directory on SDF to another location is a computer with ''ssh'' and ''rsync''/''scp'' installed and enough space to store your SDF files.

| The above would produce "/local/backup/dir/path/to/home" on the destination machine. Adding the trailing slash on the source directory would simply dump the contents of of the directory into the destination dir. | The above would produce "/local/backup/dir/path/to/home" on the destination machine.
