Nc-backup not working - free space check failed

ncp
backup

#1

Hi all,
I noticed that my NCPi hasn’t done an automatic backup for half a month despite the configuration to backup daily. I probably ran out of free space on my sd card so I removed some older backups and I checked with df -h. Although there should be more than enough unused space now (around 7GiB), running nc-backup fails.

It states:
Running nc-backup
check free space…
free space check failed. Need 10144088 Bytes
Maintenance mode already disabled
Done. Press any key…

Any suggestions on what I am doing wrong?

running NextCloudPi v1.5.1

Thanks


#2

Run nc-info or if you have a screen/keyboard attached or terminal through ssh/putty
run df -h
It should confirm whether you do or do not have enough space left.


#3

try running it without backuping your data as well…


#4

I don’t know why I haven’t tried that. I does work in that case.

I am under the impression, that it confirms that enough space should be available. Am I missing something, maybe about tmpfs ?

hi,

it’s saying that you need 10GiB, so if you only have 7GiB there’s the reason


#6

That makes sense. :see_no_evil:

I interpreted this

as needing 10+ MiB for some purposes. I don’t know why I thought that would be plausible.

I will try to backup to an usb drive and then it’s done, I guess.

Thank you all.
