Duplicity

Problem with private key to decrypt

Asked by tim-ot

Hello,

Yesterday morning (french hour) our website server burnt (OVH SBG2 in Strasboug / France), we use Duplicity for the backup, we try now to reload our website with the Duplicity files in another server. The problem is that : we have started to work with Dulicity long time ago in a dedicated server for backups, we have changed our backup server some months ago with a local one (in our building) but our developper forgot to save the private key from the first backup server, this key stayed in the first backup server which has been erased by the hoster... Now we have the backup files, the public key and the password but no way to provide the private key to Duplicity.

We are disapointed, we have worked more than 14 years on this website and everything is lost. Terrible situation.

We need your help, is there any possibility to solve ?

Best regards, Tim.

hey Tim,

unfortunately supposing you encrypted against one public key only and managed to rid yourself of possession of the matching private key you lost the possibility to decrypt. not that it helps you now, but in case you consider duplicity or key encryption in general - it is possible to encrypt against several public keys at the same time, making it possible for each of the matching private keys to decrypt later. if you add public keys of several persons, the likelyhood of losing the keys get's much lower.

good luck.. ede/duply.net

Thanks for your reply.

Do you know of a company that offers file decryption service ? We can pay.
