Once archived, the raw, original files cannot be changed. Period. Every file is timestamped and stored separately from other data.
Perpetually is built from the ground up to allow for future improvements to existing archives without compromising forensic integrity. The ability to make historical improvements is what distinguishes a professional web archiving solution.
Perpetually always stores every archived file in its original, immutable form. Unlike other ESI, web archives are best represented when stored and viewed in native format. To maximize long-term compatibility, Perpetually doesn't tie you to any particular web archiving platform or custom file format.
Retain forensic integrity during the review process with Perpetually's Self-Sufficient Export. Cryptographic hashes allow you to verify that nothing has been changed throughout the EDRM process. Perpetually's Self-Sufficient Export makes all files as immutable as a printed page.
