VerFS

=====

Simple versioning file system as Linux kernel module.

### Usage example ###

Once this Kernel module is loaded, every file deletion operation will create a backup copy:

```

  $ touch new

  $ rm new

  $ ls new*

  new#1

```

### How this stuff works ###

This Kernel module patches *sys_call_table* by replacing _open_ and _unlink_ system calls with customized versions.

### Requirements ###

1. Kernel >= 2.6.7

2. Kernel sources placed in /usr/src/linux-<version>

3. GCC

### Installation ###

```bash

make && make install

```

### Loading module ###

```bash

modprobe verfs

```

### Unloading module ###

```bash

rmmod verfs

```
