This seems a good solution! I need to modify BackupPC in order to pipe
it to 7zip right after tar'ing. Which script should I modify?

for a high-compression AES 256bit encryption you can use a tar.7z. you need
to wrap the files in tar to preserve permissions and meta data and then 7z
it with AES. 7z is also a very powerfull compressor, better than zip or
gzip and can match bzip2 but be faster. you could technically use 7zip to

At the file level of the archive or at the f
I thought of zip as a good solution for achieving encrypted backups. But
you are right here, it will lose metadata. My only requirements are that
archives must be encrypted at the file level (forget encrypted volume)
and that I can open those under Windows (using Winzip for example).

Yeah, but Tino's question was why you'd want to use zip instead of a
compressed tarball, because metadata like permissions and ownership
can't be stored in a zip file (AFAIK)

I
This is a requirement here at my company to have encrypted archives for
off-site backup.

Well, I can see WinZip 11 has support for 128- and 256-bit AES
encryption. PKZIP, on the other hand, is weak and can be cracked within
minutes.
My initial question was, anyone ever modified BackupPC in order to
archive in ZIP format instead of bz2 or gzip?

I've actually tried cracking a zipfile; and perhaps it had a strong
password, or the software wasn't very good; but I was unable to crack it
after a couple of weeks of trying.
Can't say I've done

Zip encryption is useless
Has anyone ever managed to add a functionality to archive in zip format
additionally with encryption?
Maybe a slight modification of the BackupPC_archiveHost would be
necessary or is it too complex?
