| lotuspsychj3 | good morning | 02:21 |

| ubottu | pong! | 07:52 |
| sem | Pow | 19:45 |
| sem | I have a discussion topic about Ubuntu: | 19:45 |
| sem | Say somebody wanted really easy system backups... | 19:45 |
| sem | As in, I can migrate between devices with a single click easy | 19:46 |
| sem | How would you make that | 19:46 |
| Eickmeyer | Not single-click, but really close: clonezilla. | 19:47 |
| ravage | and if you like clicking try rescuezilla | 19:48 |
| ravage | but I prefer the text mode style | 19:49 |
| sem | Clonezilla is a live-cd right? Can you make automatic backups with it somehow ? | 19:49 |
| ravage | no. and a full-backup from a running system is not the best idea anyway | 19:50 |
| ravage | you should do seperate backups of /home and the rest of the system | 19:51 |
| ravage | i use borg backup for my home backups and a seprate one for the rest. so / except home. that usually is enough to restore the system to a previous state. but does not save a bootable state of course | 19:52 |
| ravage | you should have a one-time full backup with clonezilla for that. and then you can always restore filesystem level backups on top of that when needed | 19:52 |
| sem | From a user experience perspective, my goal is the experience of completely automated backups, but downtime is ok if necessary. Is that possible with btrfs? | 19:53 |
| ravage | btrfs support snapshots | 19:53 |
| ravage | but a snapshot is not a backup | 19:53 |
| sem | ravage: can you run that root borg backup while it's running? Or does it need to be done from a live cd | 19:54 |
| ravage | there are backup tools that use btrfs snapshots for backups | 19:54 |
| ravage | i backup my / while the system is runnning yes. | 19:55 |
| sem | Ok cool | 19:55 |
| ravage | but i do not run any database server for example on my desktop | 19:55 |
| sem | Yeah | 19:55 |
| ravage | databases dont like to be backuped at runtime | 19:55 |
| ravage | and as i said that backup only saves files. not partitions or bootloaders | 19:55 |
| sem | I'm imagining an experience like with a phone | 19:56 |
| ravage | that experience is overrated too. so many apps do not get backuped completely | 19:57 |
| sem | You get the new phone, and at some point you say "restore from backup" and it just fetches (most of) your files and apps from a backup | 19:57 |
| sem | It's ok that it's not perfect with apps | 19:57 |
| ravage | if you just need your files then all you need is /home | 19:57 |
| sem | The helpful thing is it restores most of your apps and settings and all of your files | 19:58 |
| sem | It's ok that it's not perfect | 19:58 |
| ravage | if you are ok with some work to setup a backup destination ssh borg is great. restic is an alternative | 19:59 |
| ravage | https://vorta.borgbase.com/ is a nice GUI for borg | 20:00 |
| sem | Ooh I'll check it out | 20:01 |
| sem | I use restic with a rest server for my nextcloud backup, but I'm afraid to make it automatic | 20:01 |
| sem | I feel like I need to be there just in case something doesn't go right | 20:02 |
| ravage | i switched to the AIO docker image of nextcloud | 20:02 |
| ravage | im not a big docker fan | 20:02 |
| ravage | but it just works | 20:02 |
| ravage | and does borg backups automatically | 20:02 |
| sem | I would do that if I had a stronger server than a rpi4 | 20:02 |
| ravage | but if you just add a mysql and possibily postgres dump before you start your borg or restic backup you should be fine | 20:03 |
| ravage | i would set that up to a remote storage in a cron | 20:03 |
| sem | I'm using nextcloudpi which has some kind of backup built in, but I don't think it uses de-duplication so I use restic on that as well | 20:03 |
| ravage | never tried that on the pi | 20:04 |
| ravage | i tested the nextcloud snap | 20:04 |
| ravage | was not too bad 🙂 | 20:04 |
| sem | I have a nice script that automatically 1. Puts it in maintenance mode | 20:04 |
| Eickmeyer | I use the nextcloud snap in production. Works great. | 20:04 |
| sem | 2. Dumps mariadb. 3. Backs up the database, nextcloud directory, and data. 4. Takes it out of maintenance mode | 20:05 |
| ravage | with nexcloud everything that handles updates and backups for me is great | 20:05 |
| ravage | it always got messy for me on bigger system updates | 20:05 |
| sem | But it doesn't have any kind of error handling or logging so I can't just run it in cron | 20:06 |
| ravage | you could check the timestamps of that backup and some rough size checks maybe | 20:06 |
| ravage | and send you a notification if something looks off | 20:06 |
| ravage | or you look at that script and extend it | 20:07 |
| sem | I don't think I'm clever enough to write that but it's a nice idea | 20:07 |
| sem | But I'm about to replace an old family computer with a raspberry pi, and hoping to set up a backup system where it backs up over the LAN automatically, and it is easy to test the restore function. | 20:10 |
| sem | I'll look at the vorta software to see if it can do that | 20:11 |
| sem | Pika also uses borg | 23:11 |
| sem | The Borg version of resorting from backup is to copy the home directory to the new system | 23:17 |
| sem | But this still isn't great for ux because the user has to know how to create a user with that name, chown all the files for a start | 23:17 |
| sem | Not hard for a sysadmin or power user but miles away from the ez backup restore of phones | 23:18 |
| sem | This quote from YouTube: TimeMachine is one of the most important reasons I still use OSX/MacOS. It has saved me twice, once restoring from to a completely replaced drive. Not just my files but my full OS including all settings for printers, wifi and everything else. It is simply brilliant, I really don't understand why Windows and Linux don't have something similar. It is from 2007, so it completely baffles me that no other OS has been able to create | 23:35 |
| sem | something similar in 17 years... | 23:35 |
| daftykins | if you NFS mounted a user's /home from a NAS, the Pi itself would be irrelevant and you could just keep overwriting the microSD card to recover (aside from US updates) | 23:36 |
