How often do you run backups on your system? (slrpnk.net)

Basically title. I'm in the process of setting up a proper backup for my configured containers on Unraid and I'm wondering how often I should run my backup script. Right now, I have a cron job set to run on Monday and Friday nights, is this too frequent? Whats your schedule and do you strictly backup your appdata (container configs), or is there other data you include in your backups?

I honestly don't have too much to back up, so I run one full backup job every Sunday for different directories I care about. They run a check on the directory and only back up any changes or new files. I don't have the space to backup everything, so I only take the smaller stuff and most important. The backup software also allows live monitoring if I enable it, so some of my jobs I have that turned on since I didn't see any reason not to. I reuse the NAS drives that report errors that I replace with new ones to save on money. So far, so good.

Backup software is Bvckup2, and reddit was a huge fan of it years ago, so I gave it a try. It was super cheap for a lifetime license at the time, and it's super lightweight. Sorry, there is no Linux version.

Longest interval is every 24 hours. With some more frequent like every 6 hours or so, like the ones for my game servers.

I have multiple backups (3-2-1 rule), 1 is just important stuff as a file backup, the other is a full bootable system image of everything.

With proper backup software incremental backups don't use any more space unless files are changed, so no real downside to more frequent backups.

I continuous backup important files/configurations to my NAS. That's about it.

IMO people who redundant/backup their media are insane... It's such an incredible waste of space. Having a robust media library is nice, but there's no reason you can't just start over if you have data corruption or something. I have TB and TB of media that I can redownload in a weekend if something happens (if I even want). No reason to waste backup space, IMO.

Maybe for common stuff but some dont want 720p YTS or yify releases.
There are also some releases that don't follow TVDB aired releases (which sonarr requires) and matching 500 episodes manually with deviating names isn't exactly what I call 'fun time'.
Amd there are also rare releases that just arent seeded anymore in that specific quality or present on usenet.

So yes: Backup up some media files may be important.

[–] Xanza@lemm.ee 1 points 4 months ago (1 children)

Data hoarding random bullshit will never make sense to me. You're literally paying to keep media you didn't pay for because you need the 4k version of Guardians of the Galaxy 3 even though it was a shit movie...

Grab the YIFY, if it's good, then get the 2160p version... No reason to datahoard like that. It's frankly just stupid considering you're paying to store this media.

[–] Appoxo@lemmy.dbzer0.com 1 points 4 months ago (1 children)

This may work for you and please continue doing that.

But I'll get the 1080p with a moderate bitrate version of whatever I can aquire because I want it in the first place and not grab whatever I can to fill up my disk.

And as I mentioned: Matching 500 episodes (e.g. Looney Tunes and Disney shorts) manually isnt fun.
Much less if you also want to get the exact release (for example music) of a certain media and need to play detective on musicbrainz.

[–] Xanza@lemm.ee 0 points 4 months ago (1 children)

Matching 500 episodes (e.g. Looney Tunes and Disney shorts) manually isnt fun.

With tools like TinyMediaManager, why in the absolute fuck would you do it manually?

At this point, it sounds like you're just bad at media management more than anything. 1080p h265 video is at most between 1.5-2GB per video. That means with even a modest network connection speed (500Mbps lets say) you can realistically download 5TB of data over 24 hours... You can redownload your entire media library in less than 4-5 days if you wanted to.

So why spend ~$700 on 2 20TB drives, one to be used only as redundancy, when you can simply redownload everything you previously had (if you wanted to) for free? It'll just take a little bit of time.

Complete waste of money.

I prefer Sonarr for management.
Problem is the auto matching.
It just doesnt always work.
Practical example: Looney. Tunes.and.Merrie.Melodies.HQ.Project.v2022

Some episodes are either not in the correct order or their name is deviating from how tvdb sorts it.
Your best regex/automatching can do nothing about it if Looney.Tunes.Shorts.S11.E59.The.Hare.In.Trouble.mkv should actually be named Looney.Tunes.Shorts.S1959.E11.The.Hare.In.A.Pickle.mkv to be automatically imported.

At some point fixing multiple hits becomes so tedious it's easier to just clear all auto-matches and restart fresh.

Assuming it is on: Daily

[–] metaStatic@kbin.earth 2 points 4 months ago

Thanks for reminding me to validate.

Daily here also.

[–] ocean@lemmy.selfhostcat.com 2 points 4 months ago

Depends on the system but weekly at least

[–] Andres4NY@social.ridetrans.it 1 points 4 months ago

@Sunny Backups are done weekly, using Restic (and with '--read-data-subset=9%' to verify that the backup data is still valid).

But that's also in addition to doing nightly Snapraid syncs for larger media, and Syncthing for photos & documents (which means I have copies on 2+ machines).

[–] Jozav@lemmy.world 1 points 4 months ago

Using Kopia, backups are made multiple times per day to Google drive. Only changes are transferred.

Configurations are backed up once per week and manually, stored 4 weeks. Websites and NextCloud data is backed up every hour and stored for a year (although I'm doing this only 7 months now).

Kopia is magic, recommended!
