DietPi

do you have a screen attached to see where it stuck??

Hi,

how long do you wait before you power cycle?

the user data folder needs to be writable by www-data user. For the backup.sql, read permissions should be enough

not really, this just indicates that there are issues on your file system as your device has mounted it r/o. usually this only happen to protect data on a corrupted fs. Can you do a reboot and check following afterwards

Hi,

maybe this can answer your question https://raspberrypi.stackexchange.com/q ... ra-antenna

Nextcloud allow you to scan your files system for new added files, if you have copied them in place

Hi,

the access to the NAS is basically manged by SAMBA and not something DietPi is doing. You could create different folder and configure different exports based on different users.

for the VPN, which one you selected in PiVPN? WireGuard or OpenVPN?

did you already run a fsck on reboot:
Check the results, either with cat /run/initramfs/fsck.log or journalctl -t systemd-fsck.

you would need to restore the database backup you have done on the old system

ok perfect, after long journey you are back online
