Encryption Solution needed for backup tapes

[Andre Thompson_1]

Hi Everyone

Whenever I backup to tape, I need to have the data encrypted.

Does anyone have a good suggesstion/solution?

Thanks.

What backup software do you use??
some of them use propriatery data format and you do not need to use anything else.

If you are using tar/fbackup/cpio etc, then you will have to pipe it through crypt command and then put it on tape.

Something like follows.

tar -cvf - /dir | crypt > /tmp/backup
And now back up /tmp/backup

Piping is probably the most resonable way, but I'd try to collect a checksum for the backup data, ideally create a md5sum of the files backing them up and save the checksums on the tape, too.

Hi

Thanks for the responses so far. I just proposed this and my Security Engineer says that we use a RSA public/private key method.

Any more suggesstions?
