Using Incron with Git for automatic backups

Question

I'm trying to use Incron on Centos 7 to watch a directory for changes and back those changes up into a local git repo.

As a test, I've created the following:

/root/srv    <-- The live source directory
/root/git    <-- The backup location directory
/root/bin/git-autocommit    <-- The script that does the backup and move

My git-autocommit script looks like this: #!/bin/bash

REP_DIR="/root/git"       # repository directory
NOTIFY_DIR="/root/srv"    # directory to version

cd $REP_DIR
GIT_WORK_TREE=$NOTIFY_DIR /usr/bin/git add .
GIT_WORK_TREE=$NOTIFY_DIR /usr/bin/git commit -a -m "auto"

And I've made it executable.

I'm now trying to execute:

incrontab -e /root/srv IN_MODIFY,IN_CREATE,IN_MOVED_FROM,IN_MOVED_TO /root/bin/git-autocommit

but I keep getting this error:

invalid arguments - operation and source file cannot be combined

I can't exactly figure out what's going on.

Answer 1

it is probably too late for this answer, but adding a monitor is done in two steps

incrontab -e 

will open a file and in it you will add and save the command

/root/srv IN_MODIFY,IN_CREATE,IN_MOVED_FROM,IN_MOVED_TO /root/bin/git-autocommit
