Voila une config

Il "suffisait" d'ouvrir "/etc/backup2l.conf" pour edition, en root, pour decouvrir que le fichier etait pret, et ne demandait que quelques ajustements simples. Voici le mien, il fonctionne.

Mais attention a ne pas demander la lune: si la partition destinataire est trop petite, le programme refuse de continuer (logique), s'arrete (normal), et au passage rafle quelques fichiers systeme : mon acces a INTERNET s'est interrompu, il m'a fallu reinstaller un module de reconnaissance de ma carte ethernet, etrangement frappee par cette situation.

Tout est rentre dans l'ordre.

# An archive driver consists of a bash function named

{
case 1ドル in
-test)
# This function should check whether all prerequisites are met, especially if all
# required tools are installed. This prevents backup2l to fail in inconvenient
# situations, e. g. during a backup or restore operation. If everything is ok, the
# string "ok" should be returned. Everything else is interpreted as a failure.
require_tools afio
# The function 'require_tools' checks for the existence of all tools passed as
# arguments. If one of the tools is not found by which(1), an error message is
# displayed and the function does not return.
echo "ok"
;;
-suffix)
# This function should return the suffix of backup archive files. If the driver
#ädoes not create a file (e. g. transfers the backup data immediately to a tape
# or network device), an empty string has to be returned. backup2l uses this suffix
# to select a driver for unpacking. If a user-configured driver supports the same
# suffix as a built-in driver, the user driver is preferred (as in this case).
echo "afioz"
;;
-create) # Arguments: 2ドル = BID, 3ドル = archive file name, 4ドル = file list file
# This function is called to create a backup file. The argument 3ドル is the full file
# name of the archive file including path and suffix. 4ドル contains a list of files
# (full pathname) to be backed up. Directories are not contained, they are handled
# by backup2l directly without using the driver. All output to stderr should be
# directed to stdout ("2>&1").
afio -Zo -G 9 -M 30m -T 2k 3ドル < 4ドル 2>&1
# This line passes some additional options to afio (see afio(1)):
# '-G 9' maximizes the compression by gzip.
# '-M 30m' increases the size of the internal file buffer. Larger files have to
# be compressed twice.
# '-T 2k' prevents the compression of files smaller than 2k in order to save time.
;;
-toc) # Arguments: 2ドル = BID, 3ドル = archive file name
# This function is used to validate the correct generation of an archive file.
# The output is compared to the list file passed to the '-create' function.
# Any difference is reported as an error.
afio -Zt 3ドル | sed 's#^#/#'
# The sed command adds a leading slash to each entry.
;;
-extract) # Arguments: 2ドル = BID, 3ドル = archive file name, 4ドル = file list file
# This function is called by backup2l's restore procedure for each archive.
# It is extremely important that only those files contained in 4ドル are restored.
# Otherwise it may happen that files are overwritten by incorrect (e. g. older)
# versions of the same file.
