This is perfect for me as when I RAR all my files, I'm at about 22GB.

Is RAR compression secure enough? Any other options/suggestions?

Thanks,
C

Most of the files I sent there were mp3 and I didn't compressed them at all (mp3 is already quite compressed). RAR is the most efficient compression in term of space, but compressing to RAR takes more time than compressing to .zip.

Mercutio despise RAR because he finds it too time consuming.

Compression != Encryption. That said, WinRAR and Winzip both offer the additional capability to do AES-strength encryption. So if you want to protect your archive from prying eyes, encrypt + compress.

Obviously.

WinRAR offers the ability to add a password. I was wondering how secure that is.

Looks like WinRARs' encryption is pretty good:

What encryption algorithm does RAR use?


The encryption algorithm was changed to AES (Advanced Encryption Standard)
with a 128 bit key length starting with WinRAR 3.0.

The US Government created an encryption standard several
years ago, called the Data Encryption Standard (DES).
It has been widely used both in government circles and by banks.
The government has recently replaced DES with the
Advanced Encryption Standard (AES).
One cryptologist has said that assuming that you could recover a
DES key in a second (trying 2^55 keys per second),
it would take the same machine approximately 149 trillion
years to recover a 128-bit AES key.

WinRAR encryption includes parts of code from Szymon Stefanek
and Brian Gladman AES implementations and Steve Reid SHA-1 source.

The ZIP format uses a proprietary encryption algorithm.
RAR archives are encrypted by the much stronger AES-128
standard. If you need to encrypt important information,
it is better to select the RAR archive format.

According to reports, it's certainly better than WinZip 9.0, even though they both use the same type of encryption.

However, the strength of the encryption depends on the length of your password key. There are readily available utilities to crack RAR encryption that can try thousands of keys a second. You need more than 6 characters to resist this (as well as avoiding words that are in any dictionary).

7-Zip uses 256-bit AES rather than 128-bit. It's also has better compression.

However, while I'm on the subject of not believing everything you read on the net, nothing achieves appreciable compression on JPEG or MP3 files. WinRAR does have an excellent option to ignore incompressible file types (in the Compression Profile); I wish all archivers had this.

25 GB...hmm, it like my Gmail account, only 10 times bigger!

WinRar is reasonably fast with encryption, but without compression. I regularly make > 200GB backups to external drives at > 1GB/minute. It has a command line, too so a batch file can selectively backup multiple partitions, specific folders, file types, files by dates, etc. Exactly three 1.45GB spanned files will fit on a DVD for archiving.

Try this online storage service, you don’t have to go for separate compression or encryption softwares. It has the ability to compress and encrypt automatically before transferring your data, this will inturn reduce your bandwidth and time taken on file transfers over the internet.

I kinda have a feeling that most people on this forum would rather do it themselves... I've yet to see evidence that any tool can do as good a job of determining how best to compress something as I can... And as for encyption isn't half the point so that you don't have to trust the company to whome your entrusting your data...
