XSIBACKUP errors detected, but what error?

Hello,
i'm trying to use XSIBackup 9.0.1 on a ESXi free 6.5.0 (build 4887370) host.
The backup seems to end fine, but the mail subject is reporting "XSIBACKUP errors detected in backup job!!".
I cannot see any details in the mail body, where can I find these errors?

Below is a screenshot of the mail:

Many thanks,
Eros

Re: XSIBACKUP errors detected, but what error?

I don't see that notice in the screenshot you attached, maybe I'm only seeing it partially. You can copy and paste the output here.

Your speeds are very slow for what XSIBackup can achieve, try to add an SSD disk as host cache whenever you have the chance.

Thanks for the reply Daniel.
I reuploaded a complete image here:

Thanks for the tip on SSD, will consider in the next upgrade.

Here is the copy pasted result:

Re: XSIBACKUP errors detected, but what error?

Everything seems to be O.K., XSIBackup uses a temporary .ERR-XXXXXXXXX... file to store backup job errors. You probably have an empty one at your xsi-dir directory, just delete it.

I'm still worried about your speed figures, you should be getting at least 50 mb/s with commodity hardware (i3 + SATA disks), unless there is a heavy load on the server when the backup takes place.

Re: XSIBACKUP errors detected, but what error?

I cannot find any .ERR-XXXX file in the xsi executable directory:
[root@vmhost01:/vmfs/volumes/58af7e80-1ea8c5c2-373f-e0071bfff7ad/xsibackup] ls -la
total 5136
drwxr-xr-x    1 root     root          1260 Apr 22 19:37 .

-rwxrwxrwx    1 root     root        939248 Feb 23 21:56 xsibackup-rsync

The speed slowness probably is related to the datastore config.
The VM storage is a Synology NAS with a RAID5 connected via NFS.
The backup storage is a single Western Digital MyBook 1TB also connected via NFS.
I don't have local storages on this host.

Regarding the error, do you think that I can safely ignore it?

Thanks again,
Eros

Re: XSIBACKUP errors detected, but what error?

Regarding the error, if there aren't any .ERR-XXXX files you should not receive it any more. Just make sure that you list with ls -la to show hidden files (beggining with .). If you keep on getting it just let us know.

Your setup is quite common, your network could be the bottleneck. Take on account that many of these chineese 1gbps cheap brands will barely get over the 100mbps limit. We strongly recommend using Intel NICs, if you don't want to spend much, any desktop Intel card will perform much better than others. The switch is a very important piece of hardware, you don't need to spend much either, we recommend Microtik, they have amazingly performing models around 100 eur.

Re: XSIBACKUP errors detected, but what error?

Found it, it was in the datastore root, deleted now.

Host's NIC is an Intel I219-LM 1gbps, the switch is an HP 1810-8G.
Datastore NAS is a Synology DS414slim with 4 Kingston SSD SV300S37A240G 240GB in RAID5.
Backup datastore is a Western Digital MyCloud 2TB.
Don't know why is so slow.

Thanks,

Re: XSIBACKUP errors detected, but what error?

Tried another backup but the same error happened.
I have no ERR-XXXX files on the datastore, and here is the mail content:

I noticed that on the shell, before ending, it says:
Error backing the ESXi host config to /vmfs/volumes/datastore1/Backups
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Errors detected in backup, check logs
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Some warnings were raised
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Maybe are there some problems in host configuration backup? What does it means?
Thanks!

Re: XSIBACKUP errors detected, but what error?

All error reporting is done by using the .ERR-XXXX... files (note that the file begins by .)
They are not kept in the datastore, but the XSIBackup installation directory.
Behaviour is simple, if the file exists when the backup cycle is finishing and it contains more than zero (0) data, then the content is read and displayed as errors. It is previously put there by the error handling functions. On every new backup cycle the .ERR-XXXX... file is deleted and reinitialized. Just watch what happens in your installation dir and inside the .ERR-XXXXX... file while the backup is taking place.
