All, TIA. I have several years experience with duplicity, albeit not widely on multiple installations. I have used restore for directories and individual files in my old scheme and I have migrated gpg and ssh keys to a new machine and restored a home directory. Both of the following scripts are lightly edited portions of working scripts from the old scheme.

Now I am testing a new scheme so I want to ensure restore works before I depend on the backup. I am restoring a user's home directory to /home/restore/user as a simulation of what I would do if I need to restore and move an entire directory.

root@myhost:~# duplicity -V

duplicity 2.1.5

root@myhost:~# uname -a

Linux myhost 5.15.0-91-generic #101-Ubuntu SMP Tue Nov 14 13:30:08 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

#homes_restore (line not in script)

#! /bin/sh

. /root/duplicity/.passphrase

export PASSPHRASE

/usr/bin/duplicity --path-to-restore user \

--encrypt-key "key" \

--log-file /var/log/duplicity/homes/restore/test-log-`date +%d-%b-%Y-%R-%Z` \

/home/restore/

#homes_backup (line not in script)

#! /bin/sh

export PASSPHRASE

/usr/bin/duplicity \

--full-if-older-than 1M \

--encrypt-key "key" \

--log-file /var/log/duplicity/homes/backup/log-`date +%d-%b-%Y-%R-%Z` \

/home/ \

rsync://myCreds:/shark/homes/

Please point me in the right direction, I am unable to make any sense of the following when I run restore, however the directory /home/restore/user does get created. No files are restored.

root@host:~/duplicity# ./restore_homes &

[1] 80262

root@host:~/duplicity# No valid action found. Will imply 'restore' because url source was given and target is a local path.
