Open schakrava opened 8 years ago

Detect a USB device that may have a non-btrfs filesystem and provide a way to

backup Shares to it from the UI, on demand or on schedule
Transfer data from USB to a Share on demand or on schedule

An important point would be for this to support NTFS for Windows folks.

1494 (already referenced) added the following proposed roles:

"The Archive role: intended for single external drive use (eg USB). Compatible with the Redirect role. N.B. Not currently implemented"

and:

"The External Import role: intended for single external drive use (eg USB). A data synchronization role where an external drive's data is to be imported onto a designated internal share. Compatible with the Redirect role. N.B. Not currently implemented

Note: The external drive is the master source of truth. If a file is changed on the external drive and the drive is then re-attached, the next sync operation will update the designated share's version. Not the other way around. " These were intended as place holders for 1. and 2. respectively.

For the backup support I propose the following:

Backup role for a subvolume (native, ie btrfs send | btrfs receive from snapshot or a higher level of abstraction like btrbk which can take a schedule and creates appropriate timestamp folders and manages snapshots and backup retention levels)
Archive role for a disk (native, see above, just doing a recursive subvolume copy 1:1, ie btrbk archive)
Non-native Backup role for a partition on a given device/disk (non-Btrfs target like USB device, implements any rsync -av like system)
Add a new section under Storage called Backup to manage btrbk.conf schedules.

Additional interest in local (intra-install) btrfs send/receive facility has again been expressed in the following forum post. Please update as appropriate: https://forum.rockstor.com/t/using-btrfs-send-receieve-for-backups/1342/6 Noting here as relevant to @dbivolaru's previous suggestions.
