Ive always been able to restore with success fsarchiver filesystem backups, but fsarchiver does not support deduplication, and I always keep my whole system backup (excluding data home) in the cloud with duplicty over fsarchiver backups.
So i was thinking of using directlly duplicity against a btrfs snapshot filesytem, so this way i can keep my system backup updated in the cloud with just a few Mbytes of uploading, What im not sure, is how duplicity will deal with system permissions when restoring and mounting the snapshot, I know fsarchiver is the perfect tool for this purpose, but Im not sure about using duplicity.
Ho do you see this strategy??, any suggestion?

Exploring a backup strategy with Btrfs
Re: Exploring a backup strategy with Btrfs
Btrfs has deduplication in itself AFAIK. Never used it but see foe example
https://btrfs.wiki.kernel.org/index.php/Deduplication
https://askubuntu.com/questions/631917/ ... with-btrfs
Btrfs send also allows you to send snapshot diffs to a remote storage, so in theory all you want to do could he done with btrfs alone.

Hi pylkko , Im using the cloud to backup the full system, so I cant use "btrfs send"..pylkko wrote:Btrfs has deduplication in itself AFAIK. Never used it but see foe example

This is the new method Im thinking of using;being $backpath the snapshot root path
Code: Select all
duplicity -v 4 --progress --allow-source-mismatch --num-retries=5 --no-encryption --ssl-no-check-certificate --volsize 100 --verbosity=6 --timeout=60 --progress $backpath webdavs://bester@yahoo.es:"$CLK"@dav.box.com/dav/btrdup --exclude $backpath/mnt --exclude $backpath/tmp --exclude $backpath/proc --exclude $backpath/sys

Re: Exploring a backup strategy with Btrfs
btrfs send can work over ssh, but it depends on your "cloud"
Re: Exploring a backup strategy with Btrfs
We can also use rclone, or duplicity-rclone (backend) https://github.com/GilGalaad/duplicity-rclone.pylkko wrote:btrfs send can work over ssh, but it depends on your "cloud"
