XSIBackup-DC 1.5.1.9: Error code 216 signal.c Error code 1537 common.c

Hi,

My xsibackup configuration with option --replica=cbt works well over several weeks, no errors.

Last night, I found the following two errors in the backup.log.  When consulting the error.log, I did not receive any additional information, please see below:

2022-03-30T00:05:57 | Error code 1537 at file common.c, line 1537 | Error description: error running command run_backup_cmd(), returned: 1

<list of VMs backed up>), error count is: 2
2022-03-30T00:24:12 | Error code 216 at file signal.c, line 216 | Error description: raised SIGTERM (11) (2) in job, total errors: 11, check error.log

These messages above are a copy of the messages already reported via backup.log.  It appears that the second error message is a result of having the first error message, as it was stated below the last VM to be backed up where no issues occurred.

However, I wonder what the first error message means.  In fact, it concerns a VM that had been replicated without issues the nights before.  The only difference was that there was a manually created snapshot.  Does this cause a conflict with the CTK-enabled replication (--replica=cbt)?

Best regards,
Peter

All snapshots are removed when you engage a VM in a CBT job. Please, post the job if you want a more thorough analysis.
As general advice: increase verbosity and/or prepend strace to your command to have detailed system call level information on what's going on.

And here is the result:

Re: XSIBackup-DC 1.5.1.9: Error code 216 signal.c Error code 1537 common.c

The job is running OK, it's the final part where the VM is registered where you are having some issue.
Maybe some duplicate name in the registry?

You don't need --backup-how=hot, it's the default behavior.

We need some more verbosity, run the job in the command line to debug it and add --debug-print at the end to have the details on the command that fails.

./xsibackup --replica=cbt "VMs(vm)" "/backup" --options=R --quiesce --config-backup --debug-print

Update:
Looks like the problem is related to creating the remote replica snapshot. This is required to be able to switch the remote VM on without affecting the remote clone consistency and should never be deleted. It is in fact called "xsirep_donotdelete".

Your simplest workaround consists in unregistering the _XSIREP VM and deleting the clone folder from disk, this will recreate the remote cloned VM from scratch copying all data again.
