This article explains how to open Acronis Backup Gateway logs. It is required for the troubleshooting storage-related issues.

In Acronis Storage 2.0, logs were written to a .gz file. Since Acronis Storage 2.1, Acronis Software-Defined Infrastructure and Acronis Cyber Infrastructure, logs are written to a .zst file. 

Default ABGW log location:

• ACI 5.3 and higher: /var/log/abgw/
• ACI 5.2 and below: /var/log/vstorage/

Exact log location, format and default rotation can be checked in Acronis Backup Gateway configuration file, e.g.:

# grep '^log.file' /etc/vstorage/abgw.config
log.file = /var/log/abgw/abgw.log.zst

Depending on the ACI version, log will be in plain text compressed as .gz or as .zst file:

Open compressed .gz log with the following command:

# zless /var/log/vstorage/abgw.log.gz

Working with compressed .zst log is possible with zstdless, zstdcat, zstdgrep commands, e.g.:

# zstdless /var/log/abgw/abgw.log.zst

# zstdless /var/log/vstorage/abgw.log.zst
