Hi @all
since a few weeks, TFM permanently deactivates itself by no reason. Login in TNAS, I have to use the App Center to be able to reactivate TFM. Then it runs a few hours and gets deactivated again by no reason. No error logs that would explain the deactivation, no messages, nothing. I have absolutely no idea.
Edit: All software is up to date and TFM worked very well in the past. The problem are not the backup tasks but the TFM software itself, that gets deactivated

Re: [Help] TFM Backup permanently deactivates itself
As I wrote, software is up to date, so it is TFM 1.0.124 and TOS 5.1.123-00529. Device is F4-424
Re: [Help] TFM Backup permanently deactivates itself
TOS5.1.123 is not the most up to date tos 5 version, which is 5.1.145. Then Tos6.0.673 is even more "up to date" and running with TFM1.0.124 quite well.

Re: [Help] TFM Backup permanently deactivates itself
I think after the hardware-dead of my F4-221 it was a hughe error to buy another Terramaster.
Downloaded the TOS 5.1.145 - can`t be installed. Error-message says not enough space on system partition (less than 8GB). As I have no success to the system partition, it`s nothing but a big joke! Contacted support, they called me to send them a system report - mail couldn`t be delivered because it´s to large (35 MB! Yes, MB, not GB!!)
What the hell shall I do with a NAS, that´s not able to do backups reliable?!?
Apart from other problems like not correctly working access authorization, self-creating folders I only can see (and access) from Windows but not in TOS etc.

Re: [Help] TFM Backup permanently deactivates itself
Hello,We sincerely apologize for the issues you’ve encountered. Our team is actively assisting you to resolve them promptly.
Firstly, it’s standard practice for corporate email systems to impose attachment size limits, so the inability to send your 35MB system report is expected. Regarding the access permission inconsistencies and system-generated folders you mentioned, these issues typically arise due to specific hardware/software configurations.
To help us investigate, could you please provide details about the following scenarios?
1. Access Permission Issues
Affected Users/Groups: Which user accounts or groups are experiencing permission problems?
Failed Operations: Under what circumstances do permissions fail (e.g., accessing specific folders, modifying files)?
Cross-Platform Inconsistencies: Do permission issues manifest differently between Windows clients and Terramaster OS (TOS)?
Post-Reboot/Reconfiguration: Do the issues persist after rebooting the NAS or reapplying permissions?
2. System-Generated Folders
Trigger Conditions: Under what circumstances are these folders created (e.g., during backup tasks, by specific software, or after system updates)?
Folder Contents: Do the folders contain files? If so, what types (e.g., .tmp, .log, or hidden system files)?
Reproducibility Test: Can you replicate the issue by manually creating a new folder in Windows and checking its visibility in TOS?
Once you share these details, we’ll analyze the root causes and work with you to resolve the issues. Thank you for your cooperation!

Re: [Help] TFM Backup permanently deactivates itself
Hello! We sincerely apologize for the inconvenience caused. Here are our responses to your concerns:
1. TFM Deactivation Issue:
We suggest rebooting your TNAS device first to see if the issue is resolved.
2. Log Investigation:
If rebooting does not help, please send the system logs for further analysis.
If the log files are too large, you can delete the following directories before compressing and sending them:
etc>tos>scripts
etc>udev
etc>init.d
Alternatively, you can upload the logs to a cloud storage platform. Before sharing, please ensure your TNAS is connected to the internet and TNAS.online service is enabled. Upload the files via TOS File Manager, generate a share link, and provide the TNAS ID along with the share link.
3. TOS 5 Upgrade:
While we recommend upgrading to the latest version, please note that since your device was upgraded from an earlier system (original system partition was 2GB, but now 8GB is required), you can refer to this guide if you wish to proceed with the upgrade:
viewtopic.php?t=6984&sid=5d467fc0a448bd ... 0331e30522
4. Permission Issues:
You can follow the previous suggestions provided by our team or attempt the operations again after upgrading the system.
5. Remote Assistance:
If you require remote support from our engineers, please contact LiveChat to schedule an appointment.
Our working hours are: 9:30-11:30, 14:00-17:00, Monday to Friday, UTC+8.
