To backup the (or a) svn repository to the user home directory:
python hot-backup.py --archive-type=gz /path/to/svn/repository ~/
To backup the trac instance and pipe the hotcopy output to a gzipped file:
trac-admin /path/to/trac/instance hotcopy ~/my-trac-backup-folder | tar cvpzf ~/tracbackup.tgz
Also note for tar (and if working from a different folder) that the syntax runs like this:
tar cvzf /path/to/compressed-filename.tgz /path/of/folder-to-be-archived/
This will 'tar up' all the files within that particular folder (and subfolders).
And for the overly cautious - to backup *everything* from the root folder into one huuuuuge gzipped file:
tar cvpzf ~/my-filesystem-backup-file.tgz / –exclude=/name/of/folder/to/be/excluded
