Make a copy of a file when someone tries to modify the file
I wish to take a backup of the file when someone tries to modify a file say /tmp/test.txt using vi, vim, cat, copy, mv commands.
I'm aware of inotify which will notify me of any changes to the file however, I wish to make a backup before and not after the changes are made to the file.
I wish to avoid loop check and backup on the file as i believe it will be too time consuming.
Thus, whenever someone makes changes to a file there should exist its backup taken right before the file is modified.
Can you please let me know if and how this is possible to achieve ?
A solution that works across AiX / Linux systems would be great.

backupninja
BACKUPNINJA(1) backupninja package BACKUPNINJA(1)
NAME
BACKUPNINJA - A lightweight, extensible meta-backup system
"a silent flower blossom death strike to lost data."
SYNOPSIS
backupninja [ -h ] [ -d ] [ -n ] [ -t ] [ -f filename ] [ --run filename ]
DESCRIPTION
Backupninja allows you to coordinate system backups by dropping a few simple configuration files into /etc/backup.d/. Most programs you
might use for making backups don't have their own configuration file format. Backupninja provides a centralized way to configure and coor-
dinate many different backup utilities.
FEATURES
- easy to read ini style configuration files.
- you can drop in scripts to handle new types of backups.
- backup actions can be scheduled.
- you can choose when status report emails are mailed to you (always, on warning, on error, never).
- console-based wizard (ninjahelper) makes it easy to create backup action configuration files.
- passwords are never sent via the command line to helper programs.
- in order to backup a db or sql database, you cannot simply copy database files. backupninja helps you safely export the data to a format
which you can backup.
- works with Linux-Vservers.
Backup types include:
- secure, remote, incremental filesytem backup (via rdiff-backup). incremental data is compressed. permissions are retained even with an
unpriviledged backup user.
- basic system and hardware information.
- encrypted remote backups (via duplicity).
- safe backup of MySQL, PostgreSQL, OpenLDAP, and subversion databases.
- burn CD/DVDs or create ISOs.
OPTIONS
-h, --help
Show summary of options
-d, --debug
Run in debug mode, where all log messages are output to the current shell.
-f, --conffile CONF_FILE
Use CONF_FILE for the main configuration instead of /etc/backupninja.conf
-t, --test
Run in test mode, no actions are actually taken.
-n, --now
Perform actions now, instead of when they might be scheduled.
--run ACTION_FILE
Runs the action configuration ACTION_FILE and exits.
CONFIGURATION
General settings are configured in /etc/backupninja.conf. In this file you can set the log level and change the default directory loca-
tions. See backupninja.conf(5).
To preform the actual backup actions, backupninja processes each action configuration file in /etc/backup.d according to the file's suffix.
See backup.d(5).
EXAMPLE USAGE
Backupninja can be used to implement whatever backup strategy you choose. It is intended, however, to be used like so:
First, databases are safely copied or exported to /var/backups. Often, you cannot make a file backup of a database while it is in use,
hence the need to use special tools to make a safe copy or export into /var/backups.
Then, vital parts of the file system, including /var/backups, are nightly pushed to a remote, off-site, hard disk (using rdiff-backup). The
local user is root, but the remote user is not privileged. Hopefully, the remote filesystem is encrypted.
In order for this to work (ie for diff-backup to run unattended), you must create ssh keys on the source server and copy the public key to
the remote user's authorized keys file. For example:
root@srchost# ssh-keygen -t rsa -b 4096
root@srchost# ssh-copy-id -i /root/.ssh/id_dsa.pub backup@desthost
Now, you should be able to ssh from user 'root' on srchost to user 'backup' on desthost without specifying a password. When prompted for a
password by ssh-keygen, just leave it blank by hitting return. The "wizard" ninjahelper(1) will walk you through these steps.
