Consistent backup of linux vm in Veeam 12

[pazzoide76]

Hello,
I have a question about linux vm consistent backup.
I have a two node vsphere 8 cluster and have veeam 12 installed.
Most of the vm's that I have to backup have linux os.
Some vms have db's on board.
To make a consistent backup of the vm without db I have to select VMware Tools Quiescence?
While in the machines with the db do I need to script the pre/post script and use VMware Tools Quiescence?

Thank you

Greetings

Hi Simone

Enable Application-Aware Processing and use Pre-Freeze and Post-Thaw Scripts for these DB servers to prepare your applications for the VM snapshot: https://helpcenter.veeam.com/docs/backu ... ml?ver=120

For non DB servers, you can use VMware Tools Quiescence or Application-Aware Processing. If oracle is installed, please make sure to enable Application-Aware Processing.

Best,
Fabian

Thanks Fabian for the reply.
For non-db vm is it better to use VMware Tools Quiescence or Application-Aware Processing?
What is the difference?

Thank you

HI,
I tried to backup the linux vm both in application aware mode and with VMware Tools Quiescence.
When I do a restore and type the command
[root@linux ~]# dmesg |grep XFS
I get the following message back:
[ 1.104796] SGI XFS with ACLs, security attributes, no debug enabled
[ 1.107714] XFS (dm-0): Mounting V5 Filesystem
[ 1.303274] XFS (dm-0): Starting recovery (logdev: internal)
[ 1.305847] XFS (dm-0): Ending recovery (logdev: internal)
[ 1.908690] XFS (sda2): Mounting V5 Filesystem
[ 1.914632] XFS (sda2): Starting recovery (logdev: internal)
[ 1.916963] XFS (sda2): Ending recovery (logdev: internal)

On first boot the filesystem does a recovery.
It's normal?
Or is it necessary to integrate the following script?

cat /usr/sbin/pre-freeze-script
#!/bin/sh
fsfreeze -f /
cat /usr/sbin/post-thaw-script
#!/bin/sh
fsfreeze -u /

Thanks
