Hello,
I have two VMWare ESXi Server running and update them to ESXi 7.0.1.
At same time I updated XSIBackup-DC to Version 1.4.2.7
With this configuration the command --add-key brings errors ( see output below )

To find out what could be the problem I installed on one of these Servers the "old" XSIBackup-DC Version 1.4.0.0 and what a surprise, it works.
Can you give me an tipp how to solve this problem? I tried it many times, and I am sure that correct password was given!!

Output of XSIBackup-DC Version 1.4.2.7 with errors: ( below ist output on same server of Version 1.4.0.0)

Actually I have XSIBackup-DC 1.1.1.2 running.
Is it possible to update with my License to the latest version?
What needs to be done?
many thanks
Rolf

#3 Re: General matters » Backup starts before old backup ends » 2020-04-21 14:31:04

Of Course is it terrible when more than one backup Job are running at same time.
But for my unterstanding would the handling be improved when the new Job waits till old is finished or when new Job does not start when old one is still running.

Actuall we found an old Job killed in an undefined state.

Im using XSIBackup-DC 1.1.1.2 it is installed on VMware 6.7.0 Update 3 (Build 14320388)

Here I defined some cron Jobs to backup my VMs.
I can see that a Job for backup a vm to an NFS Partition was still running when a new Job for backup a different vm to the second VMware Server was started.

For me it Looks like the new xsibackup Job killed the old one, because
- snapshot on vm still exists
- no xsibackup Job is running now ( after second Job finished )
- log file has now entries that Shows the end of Job 1.

is this the designed Action that a new xsibackup Job kills an old one?

#5 Re: General matters » XSIBackup more and more tmp directories » 2020-04-13 09:34:57

Yesterday I removed all directories in tmp Today night a backup was planned which runs without Errors.
No I can see 45 directories remaining in {pri_tmp_dir}/xsi and also 45 directories in ../xsibackup/tmp
All directories have no entires. the secondary temp Directory is empty.

My configuration is:
# Primary temp dir
pri_tmp_dir=/vmfs/volumes/system/tmp

# Secondary temp dir
alt_tmp_dir=/vmfs/volumes/daten/tmp

I'm using XSIBackup-DC 1.1.1.2 it is installed on VMware 6.7.0 Update 3 (Build 14320388)
In xsibackup.conf I configured
pri_tmp_dir=/vmfs/volumes/system/tmp

after running a XSIBackup Job I can find the Directory
/vmfs/volumes/system/tmp/xsi   with Access flags : drwxrwxrwx

below this Directory there are many directories like:
2177484
2177455
2177425
….

All directories are empty.

Is it my Task to delete them before running a new XSIBackup Job?
many thanks
Rolf

#7 Re: General matters » Many Snapshots for one backup » 2020-04-11 09:25:18

The Problem is solved.
I did a wrong cron configuration because I set the Minute Parameter to '*' when hour was reached every Minute a new XSIBackup was started creates an snapshot and than stopped because it found XSIBackup already running.

So thanks for the help

#8 Re: General matters » Many Snapshots for one backup » 2020-04-09 12:24:38

Thank you for the detailed answere. I will check all mentioned Points.
By the way it happends on Windows Clients and Linux Clients and VMware Tools are installed but I will check

Im using XSIBackup-DC 1.1.1.2 it is installed on VMware 6.7.0 Update 3 (Build 14320388)
When I start an backup out of cron, sometimes I can find folowing messages in error.log

2020-04-08T02:52:44 | Error code 678 at file esxi.c, line 678
Error description: could not create snapshot in GIT-Server, error: KO

When this occured than the VM has 31 snapshots created by XSIBackup-DC after the run.
These must be deleted manually.

What means error KO?
How can I solve this Problem?

The Manual mentioned above was found in download of XSIBackup-DC

#11 Re: General matters » XSIBackup DC Manual Errors? » 2020-03-30 14:27:23

I did not use copy and paste.
I manually wrote --block-size=20M.
In my Version this does not work!!

In the Manual of XSIBackup DC you find at page 20 how to use Option --block-size

When I uses the Option as described (for example --block-size=20M) XSIBackup stopped with error

Error code 6 at file dedup-in.c, line 6
Error description: you can only use block sizes of 1M, 10M, 20M and 50M: 20

I checked it twice: config entry is 20M
When you use
--block-size=20971520
than it works.

Why does it not work as described and mentioned in Errormessage?

In Manual for XSIBackup-DC at page 3 you can see

XSIBackup-Datacenter may operate in client/server mode. When you transfer data over IP, you
must invoke the xsibackup binary on the other end. If you ommit the --remote-path argument, the
client will look for the binary in the /usr/bin folder of the remote host. You may as well indicate the
remote path by explicitly stating the remote installation path, just like you do with Rsync.

--remote-path=/vmfs/volumes/datastore1/xsi-dir/xsibackup

Question: In text is written that --remote-path should be a link to the PATH were xsibackup ist installed.
               In example it Looks for me that the value is the Programm file not the path.

What is correct? Path oder Programm file?

I started my first backup from one ESXI Server to another one. Now it runs more than 4 Hours and in the xsibackup.log only 3 vmdk files are listed with a sum of 40 GB.
how can I check that everything is OK and XSIBackup is still working?
