Hy,
After create backup in ftp mount point (success) but receive email:

Operation not supported The system failed to open the file “/mnt/ftp/tmp_fil1_1545149111_3348” for writing because of an error: Operation not supported

mount point in fstab is:

curlftpfs#usr:[email protected] /mnt/ftp         fuse rw,uid=500,user,noauto 0 0

[2018-12-18 17:06:23 +0100] warn [backup] Pruning of backup files skipped due to errors. at /usr/local/cpanel/bin/backup line 394.

what would be the solution?

Hello @H.Csaba,

This is answered on the following thread:

Backup to mounted ftp using curlftpfs

Thank you.

I understand Michael but you also understand that I do not understand how to create folders smoothly, then fold the files into folders, and then compress them in place without problems and delete the folder structure
then you can not write it in a dirty text file ...?

I write down, there is no write/read error because no backup would work either

All I did was do not write locally to the /backup local folder because SSD is in my server and I do not want an unnecessary 10 GB write on it daily!

Hello @H.Csaba,

Mounting a remote filesystem for local backup purposes is unsupported. One alternative to consider is to mount a non-SDD local drive to the server and use it for backup purposes.

Also, I encourage you to vote and add feedback to the following feature request if you'd like to see support for mounted remote filesystems for backups:

Real NFS support for legacy and new backup systems

Thank you.

It is very sad that this cPanel does not support SSD servers yet.
I'm sorry for your suggestion to use HDD instead of SSD even if you pay me!
Last but not least, my vote will not be relevant ... this step has long been done by cPanel which is not a cheap system ...

Fortunately, if you have an error message, this solution works. It's just annoying

Hello @H.Csaba,

Have you considered enabling incremental backups instead? You could store incremental backups locally, or to a remote backup destination using the rsync backup destination type.

With incremental backups, you're only adding new files to the backups during each backup generation which results in less disk writes. It also makes use of hard links, which you can read more about at:

How do the backups work exactly?

Thank you.

Hello cPanelMichael
For my wery perfect direct mounted ftp backup because my another remote server is hdd..
And this solution does not write to the local ssd server but immediately copy to remote hdd server!
So direct mounted ftp is best for daily backup! It saves 100% of the SSD from writing..
At the moment, I'm sticking to the error messages, and sometimes I delete those nasty tmp files (tmp_fil1_1545526922_26843)

I hope that this kind of rescue solution will work in a native way once..
Thx!
