Description
Troubleshooting manual backup on a FortiManager/FortiAnalyzer.
Scope
FortiManager, FortiAnalyzer.
Solution
General troubleshooting:
It is important to make sure that FortiManager/FortiAnalyzer does not have file system errors:
# diagnose debug klog
If in a command output, it is possible to find messages like 'EXT4-fs error' first complete file system check with command:
# diagnose system fsck harddisk
Executing this command will restart FortiManager/FortiAnalyzer.
System reboot will also solve a problem with a lack of space in /tmp folder, which can happen if processes were stopped unexpectedly without no chance to clear up temporary files.
It is possible to check if /tmp is full with CLI command:
# diagnose system print df
Example of manually executed backup operation:
Failed backup task will return status to a user session:
fmg # execute backup all-settings sftp 10.109.21.14 mnt/ssh <user> <passwd>
Starting backup all settings in background, Please wait.
fmg # Starting transfer the backup file to SFTP server...
SFTP failed: Error in the SSH layer <----- Error message is clearly transmitted into a logged user session.
Failed to backup all-settings due to SFTP transaction!
Backup all settings...Failed.
Successful backup task will return status into a session of user that has initiated operation:
fmg # execute backup all-settings sftp 10.109.21.14 mnt/ssh/fmg_1 <user> <passwd>
Starting backup all settings in background, Please wait.
Starting transfer the backup file to SFTP server...
Transferred 131.104M of 131.104M in 0:00:03s (36.157M/s)
