#1 Re: General matters » xsibackup removing snapshots? » 2020-01-08 18:20:54

Thanks, admin! Has anyone ever come across the loss of all their snapshots? I don't want to post my full backup logs here, but would you be willing to take a quick look and tell me if you can spot anything that would remove all the snapshots from my original VMs?

I do see sporadic error messages concerning snapshots, like this one:

Looking at the dates of the errors, this might have well happened while I was debugging this issue: DOW crontab entries execute daily and had the full backup and the incremental backup jobs run at the same time. There were no more errors after that. Could the two jobs run in parallel have cause the loss of snapshots on the original VMs?

#2 Re: General matters » xsibackup removing snapshots? » 2020-01-08 15:13:05

I think my original statement was unclear. I did not expect snapshots to survive in the backups. My report is about all my snapshots in the original VMs being lost. So, this is what's happened:

Before:

Original                    Backup
- VM1                       - VM1
  - Snapshot1
  - Snapshot2            
- VM2                       - VM2
  - Snapshot1

Now:

Original                    Backup
- VM1                       - VM1           
- VM2                       - VM2

I never expected snapshots to make it into my backups. But I did not expect to lose my original snapshots in my running VMs.

Any comments on the duplication of VMs? I did not import VMs from the backup location. Is that a side effect of XSIBackup? A malfunction?

Hi,

I'm feeling a bit unsure asking this but I have been very happy with XSIBackup Pro until I discovered this morning that all my manual snapshots of my VMs had disappeared. I have XSIBackup Pro setup to take full a backup of all VMs weekly and incremental backups of running VMs daily. I honestly can't remember whether I validated that snapshots were still there when I configured XSIBackup initially and whether I am just missing something that's logical to everybody else (that snapshots will be removed). So my question to you all here is: Is what I am seeing normal?

I also noticed that the number of VMs has doubled. It appears as if XSIBackup has duplicated all my VMs, the duplicates being named <original name>_XSIBAK and they seem to link to the files in my backup location.

VM Duplication

I don't remember seeing any errors reported in any of the daily job emails, so I am not sure what happened and where to look. Here are the two job definitions I am using:

001 - Full Backup

[root@esxi:/vmfs/volumes/f8282ebf-45634a14/xsi-dir/jobs] cat 001
"/vmfs/volumes/datastore11/xsi-dir/xsibackup" \
--backup-prog=Vmkfstools \
--snapshot=includememory \
--backup-point=/vmfs/volumes/datastore11/matterhorn/full \
--backup-type=All \
--backup-how=Hot \
--use-smtp=1 \
--mail-to=name@gmail.com \
--backup-id=001 \
--description="All VMs" \
--date-dir=yes \
--backup-room=5000 \
--exec=yes >> "/vmfs/volumes/datastore11/xsi-dir/var/logs/xsibackup.log"

002 - Incremental Backup

[root@esxi:/vmfs/volumes/f8282ebf-45634a14/xsi-dir/jobs] cat 002
"/vmfs/volumes/datastore11/xsi-dir/xsibackup" \
--backup-prog=OneDiff \
--snapshot=includememory \
--backup-point=/vmfs/volumes/datastore11/matterhorn/incremental \
--backup-type=Running \
--backup-how=Hot \
--use-smtp=1 \
--mail-to=name@gmail.com \
--backup-id=002 \
--description="Running VMs" \
--exec=yes >> "/vmfs/volumes/datastore11/xsi-dir/var/logs/xsibackup.log"

Thank you for your insights!

Cheers.
Volker

@lmasarati I know this is an old thread but still wanted to inquire if you ended up figuring this out? I just discovered this thread after creating a very similar one myself. I believe I found the solution. Here is the new thread:

@Admin, I think it would help all of us newbies if on this page the tool would call out that "7" should be avoided for the DOW:

I know this is not an XSIBackup limitation but since your software relies on the crontab provided by ESXi, this callout might save others shave hours or days off the learning curve.

Cheers!

#6 Re: General matters » DOW crontab entries execute daily » 2019-11-22 19:23:27

OK, I researched this further and it appears as if busybox cron doesn't support "7" for Sunday, only "0". At least that's what this thread indicates:

https://communities.vmware.com/thread/342106

So I will change my crontab to use "0" instead of "7" for Sunday and hopefully my jobs will no longer overlap.

#7 Re: General matters » DOW crontab entries execute daily » 2019-11-22 16:53:40

Here is the log entry, they both start at the same time and of course interfere with each other, so both complete with errors:

#8 General matters » DOW crontab entries execute daily » 2019-11-22 16:01:23

Hi,

I'm using XSIBACKUP-PRO 11.2.10 and the crontab file below to schedule 2 backup jobs:

001: Full backup of all VMs using Vmkfstools every Sunday
002: Incremental backup of all running VMs using OneDiff Monday through Saturday

For some reason, both jobs run every day and I don't understand why? Neither of the jobs is chained to the other. I hope for a simple user error on my side which a few extra pair of eyes can help me pinpoint.

These are my job configs and crontab:

001:

[root@matterhorn:~] cat /vmfs/volumes/datastore5/xsi-dir/jobs/001
"/vmfs/volumes/datastore5/xsi-dir/xsibackup" \
--backup-prog=Vmkfstools \
--snapshot=includememory \
--backup-point=/vmfs/volumes/datastore5/matterhorn/full \
--backup-type=All \
--backup-how=Hot \
--use-smtp=1 \
--mail-to=vscheuber@gmail.com \
--backup-id=001 \
--description="All VMs" \
--date-dir=yes \
--backup-room=5000 \
--exec=yes >> "/vmfs/volumes/datastore5/xsi-dir/var/logs/xsibackup.log"

002:

[root@matterhorn:~] cat /vmfs/volumes/datastore5/xsi-dir/jobs/002
"/vmfs/volumes/datastore5/xsi-dir/xsibackup" \
--backup-prog=OneDiff \
--snapshot=includememory \
--backup-point=/vmfs/volumes/datastore5/matterhorn/incremental \
--backup-type=Running \
--backup-how=Hot \
--use-smtp=1 \
--mail-to=vscheuber@gmail.com \
--backup-id=002 \
--description="Running VMs" \
--exec=yes >> "/vmfs/volumes/datastore5/xsi-dir/var/logs/xsibackup.log"

Crontab:

[root@matterhorn:~] cat /var/spool/cron/crontabs/root 
#min hour day mon dow command
1    1    *   *   *   /sbin/tmpwatch.py
1    *    *   *   *   /sbin/auto-backup.sh
0    *    *   *   *   /usr/lib/vmware/vmksummary/log-heartbeat.py

30 8 * * 7 "/vmfs/volumes/datastore5/xsi-dir/jobs/001" # Added by XSIBackup

Does anything jump the eye as to why both my jobs execute?

Thank y'all!

#9 Re: General matters » Problem with nfs share from QNAP » 2019-11-21 01:06:53

@JackiMode, did @admin's advice help?

From your command it appears to me you were already running NFS 3 or the command wouldn't have returned any response. At least on my ESXi 6.7u1 my NFS 4.1 share on my Synology NAS only shows up when using "esxcli storage nfs41 list". When I use "esxcli storage nfs list" nothing is returned.

I'm wondering because I have backup jobs getting stuck for no apparent reason and if NFS 4.1 is really the culprit, that would be an easy fix. Just looking for some confirmation before I make the switch.

@zipsonic, try:

export TERM=xterm

before launching xsibackup. This should remedy the issue as noted here:
