A tar archive is a better way to go. I wasn't sure if you had encountered tar yet so I didn't mention it. Your backup file, backup.tgz, is going to be created in the current directory. So you need to cd to destination directory first. It is going to be a very large file. Make sure you have plenty of free space in the destination. You are backing up pretty much everything.

You should make sure that you exclude the directory containing backup.tgz. You show an exclude for /backup.tgz. That implies that you plan to put the backup file in the root directory. We usually would put it elsewhere.

RDIFF-BACKUP-FS(1)					      General Commands Manual						RDIFF-BACKUP-FS(1)

NAME
rdiff-backup-fs - Filesystem for accessing rdiff-backup archives. SYNOPSIS
rdiff-backup-fs <mount_point> <repository> [repositories ...] [-option ...] DESCRIPTION
rdiff-backup-fs is a filesystem in userspace that reads rdiff-backup archives and provides convenient access. OPTIONS
--debug <0-4> Run rdiff-backup-fs in foreground with given verbosity of debug messages. -f, --full Store information about all revisions in memory. CAUTION: this may take a lot of memory if your archive contains many revisions. -l, --last Displays files from the most recent increment as directories, each holding every version of the file. CAUTION: this stores informa- tion about all revisions in memory and therefore may take a lot of memory if archive contains many revisions. -c <n>, --caching <n> How many files retrieved from the rdiff-backup archive may be cached by filesystem. By default rdiff-backup-fs will cache up to 10 files. If this switch is set to 0, no caching will be done. -r <n>, --revisions <n> How many revisions should be stored in memory for on demand revision retrieval. By default rdiff-backup-fs will store up to 10 revi- sions in memory. -d, --directory <path> Set directory for directory with temporary files. By default rdiff-backup-fs uses /tmp. -v, --version Print version of rdiff-backup-fs and exit. SEE ALSO
