This issue does not represent a security vulnerability but rather a configuration problem with Acronis backup software in the context of failover clustering. There's no risk to system security or data integrity.
The issue describes a backup problem with Acronis where it treats the same iSCSI disk as new when it moves between failover VMs, leading to excessive backups. No vulnerability or attack vector is mentioned.
Affected Systems
- Acronis Backup
Affected Versions: All versions
Remediation
- Configure Acronis to recognize the iSCSI disk by its unique identifier rather than its location in the cluster, preventing it from initiating new backups each time the disk moves.
- Check and update Acronis settings for failover clustering support, ensuring that backup jobs are aware of the shared resource nature of the iSCSI disk.
Stack Impact
This issue impacts storage configurations involving iSCSI disks in a SAN setup with failover clustering. It does not directly affect nginx, docker, linux kernel, openssh, curl, openssl, python, or homelab components.
