65373: Acronis Cyber Protect, Acronis Cyber Backup: How to change log rotation settings

Last update: 16-12-2021

Introduction

This article explains how to change the maximum size and a maximum number of stored logs for some product services on the Agent machine. This may be useful if logs take too much space, or in case you need to keep logs for longer than usual.

Solution

Acronis Managed Machine Service:

  1. On the machine with Agent, open mms.config file for editing.

Acronis Cyber Protect Cloud:

  • Windows: C:\Program Files\BackupClient\BackupAndRecovery\mms.config
  • Linux: /usr/lib/Acronis/BackupAndRecovery/mms.config

Acronis Cyber Backup 12.5: C:\Program Files\Acronis\BackupAndRecovery\mms.config

2. In the logging part of the file, find the service(s) that you want to adjust logging for and modify the following parameters:

  • maxfiles - number of log files to keep
  • maxsize - maximal log size in bytes

Example: default settings for alerts.log are maxfiles="30", maxsize="1073741824"

New settings:

3. Save changes to the file

4. Restart Acronis Managed Machine service (MMS).

Acronis Cyber Protect agent (in Acronis Cyber Cloud, Acronis Cyber Protect 15)

To adjust Acronis Cyber Protect agent log size, do the following:

  1. On the machine with Agent, open the following file for editing:
    •  Windows: C:\ProgramData\Acronis\Agent\etc\atp-agent.yaml
    • Linux: /opt/acronis/etc/atp-agent.yaml
  2. In the logger part of the file, adjust the following parameters according to your needs:

    rotation_size - rotation size, in characters

    max_files - maximum number of stored files

    min_free_space - minimum free space on the drive, in bytes

    max_size -  maximum total size of the stored files, in bytes

    To set a fixed number of log files, set max files equal to the number of log files that you want to keep, and rotation_size equal to the max_size.

    Acronis recommends keeping at least 500 MB in logs, to provide sufficient information for analysis in case troubleshooting is required. 
  3. Restart Acronis Agent Core service (aakore).
