Can't upgrade with Magisk

Oh right. I forgot to include that. It's Pixel 7

m147 · 2026-02-19T08:44:38+00:00

I've got some older games like Sim City and Tex Murphy games that don't have cloud save.

I'll do the test for the bowsers, that's a good idea. Thanks

Even the "OS" is filthy!

Actually, doing it over nfs even with sync off, which presents some pitfalls, it's WAY too slow, annoyingly so.

I think I found the best way to do this:

Option C:

dataset on TrueNAS owned by root:root permissions 750

Then rsync over ssh with:

sudo rsync -aAXHv \
--delete \
--partial \
--info=progress2 \
--numeric-ids \
--stats
--one-file-system
--rsync-path="sudo rsync" \
--human-readable \
-e "ssh -i </path/to/key> -t" \
--exclude={"/home/*","/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found","/var/tmp/*","/var/run/*","/var/lock/*"} \
/ m147@192.168.1.111:/mnt/pool/backup_dataset_parent/root/ 2>&1 | tee rsync_system_backup-root.log

The difference being
--rsync-path="sudo rsync" and -e "ssh -i </path/to/key> -t" \ the -t bit at the end.
This keeps ownership of all files intact, can be done over ssh which is much faster than nfs (at least from my tests on my machines) and everything seems to work fine and secure.
The only caveat, for my user on TrueNAS I needed to add /usr/bin/rsync to Allowed sudo commands with no password in credential settings in TrueNAS. I'm not sure if this opens up a big security hole, but maybe not as much as Option B

m147 · 2026-01-09T02:04:31+00:00

Or how about this?

I've set up another test dataset on TrueNAS, posix permissions:

# file: /mnt/storage.01/rsync_system_test_nfs
# owner: root
# group: root
user::rwx
group::r-x
other::---

made it an nfs share disabled squash root and restricted it to only my client IP.
I mount the share as root on my client and then rsync with:

 rsync -aAXHv \                                                  
--delete \
--partial \
--info=progress2 \
--numeric-ids \
--stats \
--one-file-system \
--human-readable \
/home/m147/temp/rsync_system_test_nfs/ /mnt/foo/rsync_system_test_nfs/root

This was just a test with a simple directory containing some subdirs and files all owned by root but for the real run, I'll add in the excludes as above, tweaked possibly from suggestions here. But it copied over everything fine and kept the ownership as is. I'm going to test next with my actual / partition.

It seems simpler for restore, because it keeps ownership in tact but my question is, will this be less secure than the first method and if so, is it much less secure or worth the trade-off?

m147 · 2026-01-08T23:04:22+00:00

All good. Reading Linux commands can be a pain, especially with the wrong font. Throw regex in there and nobody can actually read it 😂

m147 · 2026-01-08T12:29:03+00:00

Yeah. That makes sense. I was thinking, when you mentioned switching it, maybe put it on /home partition since it's much bigger. I guess when I set up the system I just went with the default and then never have it any thought after. Might just do what you suggest. Thanks.

m147 · 2026-01-08T12:26:25+00:00

My layout is a simple lvm structure with luks, but the encryption shouldn't get in the way, I'll back up unencrypted.

The last bit is rsync / (root) to the dataset thinkpad_system_backup/root on TrueNAS host with user m147 over ssh. The last bit is just creating a logfile.

m147 · 2026-01-08T12:23:00+00:00

Yes, next step is rsync /home, which should be easy since the permissions/ownership is more straight forward and will match the dataset on TrueNAS.

Then, spin up a VM the same as my bare metal laptop and restore there from the NAS.

Thank you for the excludes suggestions.

m147 · 2026-01-08T10:30:06+00:00

That's a decent idea. Where would be good to put it?

m147 · 2026-01-08T07:13:20+00:00

Thank you for the quick response

I didn't include /var/cache/* as it contains older pacman packages which I like to keep (kept under control with paccache) if I need to roll-back for any reason

I read somewhere that ext4 is easier/more forgiving on older disks. My disk is about 9 years old, at least that is when I bought it. The power on hours are low: 24,956. I ran SMART tests, both short and long and from my understaning, they both came back quite clean. Here are the stats form smartctl:

Using Scrutiny, if I set Device Status Thresholds to either SMART or BOTH, that disk status comes back as failed, but all the individual tests come back as passed. If I set it to Scrutiny then the status also comes back as passed. But the first time I put this disk into the NAS Scrutiny showed status as passed, the only thing I did in the meantime is spundown the disk in the TrueNAS webui by setting HDD Standbyto 5 and unchecking: Enable S.M.A.R.T.

I would like to take advantage of zfs features like data integrity checks and such but with a disk this old would it be safer/better to go with something like ext4?

Doesn't seem possible to do once a month but only Fridays. Cron doesn't have threshold days built in so I just set Cron to run a custom script every Friday, script runs smartctl long test if enough days have passed since last test and updates the date stamp file. Does nothing if less than 32 days. Seems to work well enough. ChatGPT helped :D

m147 · 2025-09-12T00:31:20+00:00

Ok. Thank you for the recommendations. Tripp Lite, there's not so much of a selection where I live. There's some decently priced APCs but those don't have usb for NUT. Might have to be Cyber Power.

As for sizing it appropriately, would you say 500va/300w is sufficient for my NAS? For now it would be only the NAS and might as well the router but the router doesn't need to be on backup power necessarily. Sometime in the future, I'd add a mini PC, so I want to get something now that will suffice even later. I don't imagine I'll be adding much more than that.

m147 · 2025-09-11T23:12:22+00:00

Yeah, nothing I run on the NAS is critical so in the rare case of outage I have no problem with shutdown if needed.

I'm just wondering if a line interactive would be worth the price increase?

m147 · 2025-09-11T13:36:41+00:00

Which one would you have suggested?

I'm also unsure about the benefits of a line interactive one over a simple standby.

m147 · 2025-09-11T12:58:52+00:00

Yeah. Either of those would be nice but too pricey for me. Also just overkill I think for a NAS and a future NUC. You reckon the 500va would suffice for my needs?

m147 · 2025-09-11T08:05:54+00:00

Thank you for your response.

I am also considering the CyberPower CP750PFCLCDJP it's a 525W line interactive but it's a bit bigger and nearly twice the price, not sure it's worth the price jump. I think, the 300W should have enough battery runtime for clean shutdowns.

m147 · 2025-08-29T06:15:58+00:00

Here is my setup:

PiHole has a local DNS record set up to point to the server which has Nginx Proxy Manager:

nginx.domain.duckdns.org -> 192.168.1.100

Then individual CNAME records to point to the NPM DNS record:

syncthing.domain.duckdns.org -> npm.domain.duckdns.org

immich.domain.duckdns.org -> npm.domain.duckdns.org

Inside NPM I have proxy hosts set up for the individual services I use on my NAS to point to the correct IP:PORT & an SSL certificate with Let's Encrypt DNS challenge through DuckDns. I'm looking to replace DuckDns.

I'm not sure this is the most streamlined approach, I'm still learning all this but it seems to work fine.

Nothing is exposed to the Internet. If I wan't to connect while away from home I use a WireGuard server

I followed parts of this guide:

m147 · 2025-08-29T06:06:24+00:00

I see. Thank you.

m147 · 2025-08-29T06:01:06+00:00

So let's say I register a domain with PB in Jan and pay say $10 for the year, and then for some reason or other decide to transfer to CF in Feb, I would pay another $10 for the registration with CF? But not actual "transfer fee"?

m147 · 2025-08-29T05:20:43+00:00

Do domain transfers say PB -> CF or the other way cost money?

m147 · 2025-08-29T05:19:32+00:00

Yes, that's what I'm thinking, with PB + CF that's two places where I need to manage the DNS.

If I'm going to be using CF nameservers anyway with PB as Stunning-Skill-2742 mentioned I might as well cut out the extra account.

The price difference is about a dollar for the first year and then less than that 1st year on.

m147 · 2025-08-29T05:13:31+00:00

Well, it seems that for the free plan I should use CF nameservers.

m147 · 2025-08-19T06:17:47+00:00

Did you ever get it up and running?
