Its parity information so in case a couple bits get flipped in the backup files, the parity information can be used to restore the data See https://en.wikipedia.org/wiki/Parchive It should work on the ‘final’ output of the backup, so I feel like it should work if the backup isn’t encrypted and its just a .tar.gz file, but I have not tried it ~Mark From: MRob via Duplicity-talk Is par2 like a tar format with extra bits added to facilitate recovering corrupt files? Is protection against files corrupt inside the archive or corrupt archive file itself? Is there a easy to understands overview? I see to use it like "par2+gs://bucket" but I want to do some local backups that will use --no-encryption option and transport over sftp. Is still a good idea to do like "par2+sftp://address@hidden/path"? If par2 is very powerful ability to protect against corruption, why isn't it promoted more regular on duplicity website, manpage, mailing list? Shouldn't it be in more of the examples? _______________________________________________ Duplicity-talk mailing list address@hidden https://lists.nongnu.org/mailman/listinfo/duplicity-talk |
