How to recover deleted files in AIX in 3 steps
When a file is deleted on AIX, its contents isn't immediately destroyed. AIX only marks the hard drive space as being available for use, so the data is still there. With the undelete tool from Compunix, you can recover easily that deleted data.
This tool works in all disaster situations were data and files have been deleted, some examples:
- a user typing 'rm *'
- your system was compromised and some files have been deleted
- a software bug erased files
- crfs was executed on an existing JFS2 filesystem
- any other case where files have been deleted
To recover your data, follow these three steps:
- Step 1 : freeze
In order to optimize recovery chances, it is important to take no actions that could worsen the situation. Filesystem on which deletion occurred should not be modified or updated.
- Download the free tool for your AIX version. This tool is a small program that lists you all files that can be recovered.

When you see files and data that you want to recover, purchase and download the full licensed version, and start immediately with the restoration of your data.
The analyse utility will check every bit and byte and uses multiple algorithms to recreate the original data. If the free tool shows recoverable data, the licensed tool will be able to recover your data.
