backup fails

[reshef]

Hello,

I have a 300gb server with 115gb used and 164 available.

the backup keeps failing:

User admin has been backed up. <23:30:10>
Error Compressing the backup file user.admin.blabla.tar.gz :
gzip: stdout: No space left on device
/bin/tar: /home/tmp/admin/blabla/user.admin.blabla.tar.gz: Wrote only 8192 of 10240 bytes
/bin/tar: Error is not recoverable: exiting now


How can it fail when there is more available than consumed disk space and what can I do about it? can I increase the compression level?
The server is used as a mail server.

Hello,

How is your disk space allocation on partitions?

What do you see with

df -h

df -i

?

[root@da-mail ~]# df -h

/dev/sda3 291G 114G 163G 42% /

The server is also monitored so I see that it's just reaching 0% disk space during the time that the backup runs
