I'm sure the cause of the problem is within KeyHelp
(Problems not related to KeyHelp belong in the Offtopic forum)


Server operating system + version
Debian 11.3 (64-bit)


Server virtualization technology used
KVM


KeyHelp version + build number
22.0 (Build 2393)


Problem description / error messages
Backup worked fine until Apr 3, 2022, but after this time, fallback with this message:
Expected result
Backup everything to external backup server with SFTP connection.

Actual result
Canceled backup with error message.

Steps to reproduce
Backup schedule management, every day at 3:00AM.


Additional information
Total used: 83.62 GB. External backup server have 300 GB space.

Local server will be 50% free space to make backup to external FTP? I read on this forum that it is not neccessary 50% free space. Backup system will cache and save directly to the FTP.

Hello,

can you please post the backup settings (or screenshots) for this backup task.

This was only relevant for the old backup system, the new one does not have such high demands (some free space is still necessary)

Hello,

expanded space +50 GB yesterday. Now: Free: 57.21 GB Used: 80.11 GB Total: 144.69 GB

Changed backup snapshot from 5 to 2. Backup ran successfully as last night. The snapshot was the fault or the space?

Are you backing up a lot of email data? For this purpose there is a significant amount of disk space, which needs to be available during backup.

Yes. ~55-60 GB was email data. So if i will backup these datas, server may have more free space than 55-60 GB?

Unfortunately yes, this is is necessary due to file permissions.

The email data is prepared and stored internally as tar.gz archive, before it gets backed up.
As email data is only text, it should compress rather good, but with 55-60GB in emails it will still take a big chunk of disk space.

I got it. Thank you for reply.

Have a nice day!

Hi Alexander,

I found this issue, because I ran into the same problem some days ago.

I have one additional question. Is it possible (e.g. with some special configuration on the server), that Keyhelp is creating the tar.gz archive not on the primary drive but on an additional drive (maybe sdb).

Best regards,
Andi

You can set a mountpoint for the backup temp directory so that its stored on sdb.

Hello,

The directory, where all the data will be prepared is /backup-keyhelp/
So if you put this on a separate drive, you should be good to go.


Additional info: Default location for local backups is /backup/.

Thank you very much for your tipps. I will give it a try!!

Best regards,
Andi
