In fact, there is information about it, my fault. But probably warning or error in a log while XSI starts and checks source and destination datastore and VMs will be more helpful and time-saving of frustrated users;)
Thanks for help and involvement.
#2 Re: © OneDiff » ERROR DIFDELAL on snapshot remove » 2019-01-07 00:16:01
And finally, I found "The bug" Problem was in the file system, source datastore is VMFS5 destination VMFS6. So XSI made snapshots in another way, using a mechanism that not supported, or incompatible with VMFS6. After moving VM to VMFS6 everything works well. I don't find any mention about that in the documentation.
Thanks for a good point to look at the logs. In hostd.log I found that lines:
DiskLib_IsVMFSSparseSupported: vmfssparse is not supported on /vmfs/volumes/5b5fff52-bf239984-debc-a4bf012da28c/VM_BACKUP/Ubuntu: f532.

#3 Re: © OneDiff » ERROR DIFDELAL on snapshot remove » 2019-01-06 19:45:11
Maybe that is a generic error, but why only on copies that were done by XSI? No process doesn't lock snapshot files. When I wipe Ubuntu.vmsd content and made a change in VMX file (change disk file name to Ubuntu.vmdk), creating and deleting new snapshots works well. So I assume "snapshot subsystem" must work well. The only snapshots created while OneDiff copy doesn't work, is it do that in another way than a manual snapshot from GUI?
BTW esxi host was rebooted many times.

When I try to remove all snapshots from Ubuntu _XSIBackup VM manually from ESXi web interface I've got an error:
Failed - A general system error occurred: vim.fault.GenericVmConfigFault
When I delete Ubuntu_XSIBackup VM from GUI he left in VM directory two files, looks like they are not treated as part of VM:
Ubuntu-000002-delta.vmdk
Ubuntu-Snapshot1.vmsn
In ESXi Web GUI Ubuntu_XSIBackup has disk [datastore_d2] VM_BACKUP/Ubuntu/Ubuntu-000002.vmdk, capacity 0 B
Also, I noticed Ubuntu_XSIBackup has no VMX file, only "Ubuntu.vmx.bak" after renaming to Ubuntu.vmx i can reregister VM, but can't start, error:
Cannot open the disk '/vmfs/volumes/5b5fff52-bf239984-debc-a4bf012da28c/VM_BACKUP/Ubuntu/Ubuntu-000001.vmdk' or one of the snapshot disks it depends on.
So it looks like a problem with the proper chain of snapshots, but this happens only with snapshots created with XSI OneDiff copied VM's. Snapshots of source VM's are created and deleted without any problems, also manual snapshots. What was could suddenly happen to ESXi snapshot subsystem, that hits only XSI functions, what can I do more?

After a few months of fully successful backup on ESXi 6.5 (Build 7967591) I, unfortunately, got errors while making OneDiff copies. If I remove backups from the destination and make new initial backup everything works well, but the next backup fails while XSI tries to remove a snapshot from newly created _XSIBack, no matter from the source VM is powered on, or off. Obviously, I tried with host reboot, checking free space etc. also I have checked these solutions: https://33hops.com/esxi-snapshot-errors … tions.html. Source VM before make initial backup has no snapshots, and has only one vmdk. After spending a lot of time on various testing I've got no clue, what happened. Please for help.

"not one in a million" is the reply for "The GUI is more than tested" 
I've found version 10.3.2 on my disk, as always works without any problems, maybe version 11 in future will be more polished, but now anytime i touch that edition, i've got problems, as you can see, not only me.
#7 Re: General matters » XSI 11.0.2 GUI stopped working » 2018-08-21 20:14:32
It is really hard to find resolution for "unexpected redirection"? As you can see this situation it's not "one on a million" I'm was using XSI for few years without any problems, until now, this time (from version 11) contact with XSI Backup is really frustrating.
Where can i find older versions, without GUI?
#8 Re: General matters » XSI 11.0.2 GUI stopped working » 2018-08-21 16:11:19
new server, new ESXI(now 6.5), new clean installation, and after while wiggling thru GUI, the same problem:
/vmfs/volumes/datastore1/xsi-dir/src/pro/menu/main: eval: line 1: syntax error: unexpected redirection
for me there is much more problems with GUI than before, without GUI. I want use it, but i cant grrrr. Unfortunatly i can't reboot my host, just like that, i've got there services that need to be online 
How can I add jobs to cron in old good cli way?

I don't know why, but suddenly my XSI GUI stopped working properly, when I choose "Manage Backup Jobs" from menu, XSI exits with error:
/vmfs/volumes/datastore1/xsi-dir/src/pro/menu/main: eval: line 1: syntax error: unexpected ")"
First I thought that may be a jobs files problem, but after removing them error still remain
My installation is esxi 5.5, XSI started from command line works with no problem
how can I start jobs directly from command line?
#10 Re: General matters » Cron job works, but xsibackup-cron.log is empty » 2018-02-14 22:23:23
Now after I removed sed call everything is OK, without host reboot. Thank you! 
#11 Re: General matters » Cron job works, but xsibackup-cron.log is empty » 2018-02-13 11:00:23
Ok, there's a trace. After xsi finished execution, xsibackup-cron.log appears and looks OK, there's all job execution log! So it loks like a problem with real-time output redirection to file, maybe it's buffered somewhere, and xsi writes it after execution? So how can i force xsi to dump log in real-time?
#12 Re: General matters » Cron job works, but xsibackup-cron.log is empty » 2018-02-11 12:06:38
If I delete file "xsibackup-cron.log" it appears after minute or two, so for me cron service works, and looks for file in proper place. More over, backup job starts if I set job in xsibackup-cron, but it dosen't write outs to xsibackup-cron.log I was tryed reinstall cron by ./xsibackup --install-cron, restarted cron service. Everything looks ok, but cron log is still empty. Last chance for me is host reboot, but i'm still looking for better resolution, because as I mentioned it's not so easy in my case
#13 Re: General matters » Cron job works, but xsibackup-cron.log is empty » 2018-02-11 11:46:13
ESXi 5.5.0 2068190, before upgrade, with XSI version XSIBACKUP-FREE 9.1.9 everything worked well. I'll try to reboot Host, but its not so easy, there are VM's that needs to be still online. Maybe restart cron service? or this is not a reason?
#14 Re: General matters » Cron job works, but xsibackup-cron.log is empty » 2018-02-10 19:21:19
In few steps:
-I downloaded new installation via provided script, then I renamed xsibackup(my old xsi dir) to xsibackup_.
-I renamed xsi-dir folder name to xsibackup
-I was started ./xsibackup, there was an license agreement request, and script was looking for VM, so I stoped it by ctrl+c.
-I generate license key via web site, and put it in xsibackup dir
Then I added line with commands to xsibackup-cron, with additionally "--backup-prog=onediff" switch and changed start hour to actual, plus few minutes. Xsi was start to works, xsibackup-cron.log appears but is still empty
as I mentioned before actual version is XSIBACKUP-PRO 10.2.8

Hello,
After upgrade from XSIBACKUP-FREE 9.1.9 to XSIBACKUP-PRO 10.2.8 i've got problem with xsibackup-cron.log, everything is working, PID is visible in xsibackup-pid, vSphereClient shows information about snapshots etc. but xsibackup-cron.log is still empty, why?
