What is your backup and restore method?

@Lusbueb I have a Buffalo NAS LS I am trying to backup too but can’t figure out the right path to add to sudo nano /etc/fstab

@Lusbueb this looks interesting.

Do you stop mm before the back up?

The only information that is unique to my mirror is the module configuration. I just back up the config.js file whenever I make a change to the mirror configuration. If the mirror needs to be rebuilt, I can quickly build a slick Buster installation, SSH into the Pi, run the installation script, drop the backup config.js to the config folder and then do a half-dozen git clone commands.

Once the mirror is up & running, I can do the boring maintenance stuff (apt get update && apt get upgrade) and just let it run in the background.

@swvalenti on my Netgeras ReadyNAS i have enabled NFS and SMB and a Share named backup (everyone has full-access)

i start the raspibackup.sh-Script with this helper-Script named raspiBackupNfsWrapper.sh

#!/bin/bash

Will this be helpfull for you?

@BillyTheKid9588 yes, in the raspiBackup.conf i have this to lines to stop an start MM:


# commands to stop services before backup separated by &
DEFAULT_STOPSERVICES="sudo -u pi pm2 stop mm && systemctl stop lighttpd"

# commands to start services after backup separated by &
DEFAULT_STARTSERVICES="systemctl start lighttpd && sudo -u pi pm2 start mm"

Will this be helpfull for you?

Regards Peter

For my backup I tried to just make an image of my card, so if something were to ever go wrong, I could just reimage my card and it would work. Well, we lost power yesterday, and something went wrong. I formatted the card, re imaged it, and it eventually booted after some errors. The problem was that my config.js was corrupted or something, because I couldn’t edit it anymore. I’ve tried to reimage it again, but i’ve now gotten a different set of errors and a debian load screen i’ve never seen before. No idea where I went wrong.

@Cyric there is a false sense of security w sd cards. the memory technology used is write once. the bits cannot be reused

the software does not know this… the hardware does the work under the covers and say Success!
even when its not.

once the bits are used, the card is dead. may turn read only or may start exhibiting corrupted files ( the software does not know)

this technology is great for cameras and music, low write activity… not so much for os’s that page, write log files… or apps like mm that constantly cause log files

I think, based on your description your card is used up. time for a new one…

I changed my pis to boot from SD card, but run from ssd (same technology, just really bigger)

ps. I have lost 10 sd cards to this problem over the last 4 years…

pastormingle

@sdetweil I have a 32gb UHS-I that has my current configuration that I wanted to backup and also clone it to a new ssd that is same type and size… My question is this I have cloned it but when I copy it to the new ssd it says that it isn’t the same sizes… But it is the same type of card… Can the image be reduced? What can I do to clone to a new ssd?
