# A few notes about includes and excludes:
|
|
# 1. include and exclude statements support globbing with '*'
|
|
# 2. Symlinks are not dereferenced. Moreover, an include line whose path
|
|
# contains, at any level, a symlink to a directory, will only have the
|
|
# symlink backed-up, not the target directory's content. Yes, you have to
|
|
# dereference yourself the symlinks, or to use 'mount --bind' instead.
|
|
# Example: let's say /home is a symlink to /mnt/crypt/home ; the following
|
|
# line will only backup a "/home" symlink ; neither /home/user nor
|
|
# /home/user/Mail will be backed-up :
|
|
# include = /home/user/Mail
|
|
# A workaround is to 'mount --bind /mnt/crypt/home /home' ; another one is to
|
|
# write :
|
|
# include = /mnt/crypt/home/user/Mail
|
|
# 3. All the excludes come after all the includes. The order is not otherwise
|
|
# taken into account.
