[Dar-support] Backup in Windows XP

[Joacim J <joc...@gm...>]

I am writing a shell script that runs on windows XP OS and Cygwin

For testing purpose I have a folder called "C:\Temp\My Folder". I will
not make backup of the complete file system, only selected folders
(incl. subfolders).

The backup script is at C:\ looking like:

#######################################
#!/bin/sh

BACKUP_ARCHIVE_PATH=3D"Filez/Backup/Archive"
BACKUP_ARCHIVE_FILE=3D"Backup_`date '+%Y-%m-%d_%H.%M'`.tar.gz"
BACKUP_CURRENT_PATH=3D"C:/Filez/Backup/Current"
BACKUP_FILE_FULL=3D"Backup_Full"

BACKUP_FILE_INCR=3D"Backup_`date '+%Y-%m-%d_%H.%M'`"

BACKUP_ITEM=3D"Temp/My Folder"
BACKUP_LOG_FILE=3D"Backup_`date '+%Y-%m-%d_%H.%M'`.log"

#####################################################################
# Usage
#####################################################################
usage() {
    echo "Usage"
}

#####################################################################
# Pack and store old backups
#####################################################################
packAndStore() {
    echo "Packing old backups and store them at
${BACKUP_ARCHIVE_PATH}/${BACKUP_ARCHIVE_FILE}"
    tar cfz ${BACKUP_ARCHIVE_PATH}/${BACKUP_ARCHIVE_FILE} ${BACKUP_CURRENT_=
PATH}
    echo "Packing/Store finished"
}

#####################################################################
# Clean current backups
#####################################################################
clean() {
    rm -f ${BACKUP_CURRENT_PATH}/*
}

#####################################################################
# Make a full backup
#####################################################################
makeFullBackup() {
    echo "makeFullBackup"
    cd c:/
    CMD=3D"dar -c ${BACKUP_CURRENT_PATH}/${BACKUP_FILE_FULL} -s 4490M -S
4485M -v -g \"${BACKUP_ITEM}\""
    echo ${CMD}
    ${CMD}
}

#####################################################################
# Make a incremental backup
#####################################################################
makeIncrementalBackup() {
    echo "makeIncrementalBackup"
}

#packAndStore
clean
makeFullBackup
#######################################

The output when running the script is:

#######################################
C:\>bash backupFull.sh
makeFullBackup
dar -c C:/Filez/Backup/Current/Backup_Full -s 4490M -S 4485M -v -g
"Temp/My Folder"
The [list of path] is deprecated, thanks to use the -g option instead

This message is reported when a command line word is given out of
options argument, as you guess. This is strange for the given
command-line as the "Temp/My Folder" seems properly quoted seen what is
displayed. But it depends how the shell passes the arguments to dar (it
could pass it this way: ... [-g] ["Temp/My] [Folder"]

I suggest you call the exactly same command but directly from an
interactive shell, if all works properly, this becomes from the way
arguments are passed from the shell to dar, we will then see how to
workaroud that.

the fact that you have nothing saved is a consequence of this previous
problem.

Denis is exactly right: dar is seeing <<"Temp/My">> as the argument
for -g, and <<Folder">> as an extra argument.

Try:

    echo ${CMD}
    eval ${CMD}

Yes,
Replacing
${CMD}
with
eval ${CMD}

Did the trick!

Now I can proceed with my setup, tanks!
