Issue Encountered During File Backup for Espo CRM Instance Upgrade

[sapyantuk]

Hello Developer,
I hope this message finds you well. I am currently using Espo CRM version 7.3.4 and I am interested in upgrading my instance to the latest version of Espo CRM.
In my preparation for this upgrade, I have been attempting to back up my instance. I have successfully backed up the database. However, I have encountered an issue while attempting to back up the files located under the "public_html" directory using the command:

tar -xzf "files.tar.gz" -C /var/www/html

When I input this command in the command line interface (CLI), the process begins to generate the files, but at some point, an error message appears stating: "file changed as we read it."

Unfortunately, this issue prevents me from completing the backup process for the file directory. I am unsure about how to proceed and would greatly appreciate your guidance on how to resolve this error. My ultimate goal is to successfully create a comprehensive backup that will allow me to proceed with the instance update.

Thank you in advance for your assistance and expertise.

Best regards,
Yubraj Kafle

Hi
maybe enable Maintenance Mode first?

Hi sapyantuk,

Please try to back up your instance with a script:
