[rdiff-backup-users] Information
Good morning Sir, I am working on a project which consist to use rdiff-backup to make backup of data on line. So looking on internet i don't find anyway if rdiff-backup can make encryption component of data send Reason why i contact you, thank you for yor help.

Hopefully you are interested in linux, because encfs is difficult to use on windows or mac. If you use encfs for a solution like this, it would be similar to this: You have an encrypted directory, which is encfs mounted plaintext. You specify the plaintext directory as the rdiff-backup destination. And then you sync the encrypted directory online. This does consume disk space, as multiple copies (encrypted and non-encrypted) get stored on your local disk. But it works. ___ rdiff-backup-users mailing list at rdiff-backup-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/rdiff-backup-users Wiki URL: http://rdiff-backup.solutionsfirst.com.au/index.php/RdiffBackupWiki
Re: [rdiff-backup-users] Information
Bonjour Ibrahim rdiff-backup does not have any built-in encryption. Also based on my experience rdiff-backup should not be run directly over the internet, it should be run on a lan (or of course a single machine) and then the rdiff-backup repository (archive) mirrored over the internet using rsync. This works very well for maintaining offsite data backup and the internet transmission is secured with ssh. This approach is used by my TimeDicer package (http://www.timedicer.co.uk). However this assumes that both source and destination are secure. It is possible to wrap rdiff-backup in some encryption e.g. with encfs or ecryptfs. Another option is to look at project duplicity http://duplicity.nongnu.org/. Duplicity grew out of rdiff-backup, however: -rdiff-backup's archives are meant to be as easy to view as possible, while duplicity's are as hard to view as possible and can be encrypted with GnuPG - duplicity saves data in the more conventional full+forward delta format instead of rdiff-backup's mirror+reverse deltas - rdiff-backup requires another copy of rdiff-backup on the remote destination, while duplicity currently supports local file storage, scp/ssh, ftp, rsync, HSI, WebDAV, Tahoe-LAFS, and Amazon S3 Note: the use of forward delta/diff format by duplicity means that recovering data from the most recent incremental backup requires a complete undamaged set of incremental backups from the original full backup until the most recent date; in order to reduce this dependency and the associated risk many duplicity users carry out new full backups every month or so, but this means you lose all your older backups (or if you retain them and create a parallel new archive you lose most of the advantage of the delta storage). rdiff-backup, by contrast, stores the most recent backup 'in the clear' so it is always easy to retrieve (not even requiring the use of rdiff-backup itself), and the backup increments apply in reverse order, so most recent backups are inherently safer and older backups more vulnerable.

[rdiff-backup-users] Recovery to Linux from Windows
Our Linux box died, so now we're restoring from a rdiff-backup repository on a Windows box running Cygwin. Fine for lowercase files. But not fine for uppercase escaped files. I see lots of posts about why capital letters are escaped and from the FAQ I see "Upon restore (from the Mac backup server to the Linux system), the filenames are unquoted and you will get "MyFile" back." However, I'm unable to get the filenames back to normal using a restore command (-r with a time seems to be the only restore command there is for rdiff-backup) Any ideas? A script to un-escape the names would be fine as an alternative if anyone has one... Details below: ;080roducts contains ;065;084;067ontent;084ypes/ ;065;084;082eference;066rowser;087idget/ ;065rchetypes/ ;067;077;070;065ction;073cons/ ;067;077;070;067alendar/ ;067;077;070;067ore/ ;067;077;070;068efault/ ;067;077;070;068ynamic;086iew;070;084;073/ ;067;077;070;070orm;067ontroller/ ;067;077;070;080laceful;087orkflow/ ;067;077;070;080lone/ ;067;077;070;081uick;073nstaller;084ool/ ;067;077;070;083etup/ ;067;077;070;083quid;084ool/ etc...
