BACKUPMON BACKUPMON v1.5.10 -Mar 1, 2024- Backup/Restore your Router: JFFS + NVRAM + External USB Drive! (**Thread closed due to age**)

Sorry my friend. After a couple of reboots, it solved. It was hanging somehow connecting to my NAS.
Sorry to not test it properly before starting whining

This old router has feelings and sometimes he needs to rest unplugged from the outlet

Not a problem! I completely understand, being an RT-AC86U owner myself. This router has quirks, and was afraid you may have hit that "nvram get" bug that completely locks up any script. Was hoping not to have to address workarounds in the script for the 86U again.

With the purge at the default (90) I was wondering about the actual space being used on my NAS. I needn't have been concerned - 11 backups and still less than 1GB, tonight will break that.
Just putting it out there (and giving a wee bump to the thread in the process).

WOW! What do you have on your drive! LOL. For comparison's sake, I've got 31 backups going, and totaling about 573MB.

Look at my signature, and consider that I set everything possible to store data on the usb rather than jffs. So that includes data for Diversion, spdMerlin and others.

Makes complete sense now!

Why would it matter whether you store to jffs or USB as far as backup size? Both are backed up by the backupmon script. Unless I'm missing something...

 

[Ripshod]

I only have a 63MB jffs partition. Since starting the backups the chart data and all that has blown ssd usage up from 45 to 131MB. If that data was stored to jffs without any cropping I'd have hit some kind of out-of-memory condition days ago.

mmmmm, some kind of realisation just hit me. @Viktor Jaep those users who are experiencing slowdowns and random reboots, could they possibly be filling the jffs partition with this data? Or is that just too simple?

I wouldn't doubt that an out-of-control jffs would have some effect on router stability for sure! I'm only using 3MB. Keeping it lean!

@Viktor Jaep A lean, mean fighting machine!

LOL! After experimenting with so many scripts over the years, I'm determined to just use the K.I.S.S. method to radically reduce the amount of frustration and hairpulling incidents.

 

[Viktor Jaep]

That's actually an interesting factoid... who or what determines the jffs partition size? You're on a AX88U with a 63MB partition. I'm on a new GT-AX6000, with only a 44MB partition size. Do these models truly come with such varying memory sizes that they cannot even agree on a standard jffs partition size?

 

[Ripshod]

I don't try to understand Asus' reasoning but an interesting read about jffs here

Jffs

Third party firmware for Asus routers (newer codebase) - RMerl/asuswrt-merlin.ng

github.com

It's really interesting that frequent writes should be avoided or face an untimely death. Another penny's just dropped. I assume failing flash would definitely, eventually kill a router that uses jffs for data storage rather than usb. Not that I want to worry anyone. This is just supposition.

Oh boy... thanks for that! Now I'm going to be freaking out about what's frequently writing to my jffs...

And I read that the newer devices (e.g., GT-AX6000) do not use JFFS, but rather UBIFS (another memory technology), which may also be part of differing partition size.

Thanks! I will definitely sleep better at night now knowing UBIFS has got my back!

 

[Ripshod]

Yeah. jffs and UBIFS are just the filesystems, the hardware is still just flash - that's how I read it.

Hi Jaep,

Sorry I’m late to the party. So many replies in short time of release!!! If I have BACKUPMON, and my ever heating usb sticks fail, I can make the jump to ssd/hdd. But is there a way to do this deliberately and not wait for it to fail?

That would work, so long as it's formatted to ext4 using amtm and has the same label.

Perfect! Thanks Ripshod
