rationale Link to heading
- do not send your phone backup to nonexistant privacy policies company
- host on local truenas + webdav
- using davx app for webdav + caldav/cardav
- using https for the transport what else ?
- using truenas webui for kiss
requirements Link to heading
- a local truenas server 192.168.30.35
- a lineageos phone that reach this server:port
warnings Link to heading
- the seedvault is not a single/perfect solution at all !
you need a second simple backup solution (adb/syncthing/whatsoever) in case seedvault does shit while backup/recovering
adb seems to be a solid solution
reading this excellent blogpost can help
- if you need to use a public facing webdav server ( not covered in this post )
it’s highly recommended to use caddy mothafuckin KISS stuff
truenas setup Link to heading
create a dataset called webdav Link to heading
install app webdav Link to heading
-
webdav
-
basic auth
-
username
-
passphrase
-
user and group
-
uid of webdav is 666
-
gid of webdav is 666
-
enable https
-
:30035
-
truenas defautl certificate (or create your own)
-
enable the share
-
share name thawebdav
-
hostpath /mnt/your/dataset/webdav
-
install/update
it could take long time before app is deployed via kubernetes refresh the app webui to check it out
check what webdav guid is it’s 666 don’t ask me why
Link to heading
apply permission in your dataset as follows
-
root rwx rwx rwx
-
webdav rwx rwx rwx
-
others gofuckyourself
-
apply permission recuresively
-
save
restart the webdav app Link to heading
troubleshooting Link to heading
you can mount the webdav from your laptop
sudo mount.davfs 'https://192.168.30.35:30035' /mnt/thawebdav/
you can also reach it via cadaver
cadaver https://192.168.30.35:30035
lineageOS setup Link to heading
davx thing Link to heading
- connect to your homenetwork to reach 192.168.30.35:30035
- double check your firewall is not an issue
Install the davx app via fdroid
https://f-droid.org/packages/at.bitfire.davdroid/
-
skip the tips
-
in the main menu > tools > add a webdav mount
-
name : thawebdav
-
url: https://192.168.30.35:30035
-
username
-
passwod
-
add
if you have 302 error double check you have correct url
you should see it added to your mountpoint
seedvault thing Link to heading
In System > backup > seed vault setting
- generate recovery code
- backup tha code !
- apply it
- setup the destination as davx webdav
- check all the box you want
you can add specific directories when checking backup files
wait for seedvault to do some backup then check if it’s in your webdav app
for some reasons you may need to fully restore seedvault before following the setup procedure
- settings > Apps > display system apps > seedvault
- delete cache and data
- force stop
- reconfigure seedvault from scratch
restore backup Link to heading
you can use this adb command from your laptop
adb shell am start-activity -a com.stevesoltys.seedvault.RESTORE_BACKUP
or this code on the phone
*#*#RESTORE#*#*
then hope it’ll go well !
