Rollback Issues – Fix Time Desync in Proxmox, DBs and Fedora

Av Alicia Möller · april 7, 2026

Understanding and Fixing Rollback Issues Across Systems

Rollback operations across virtual machines, databases, and operating systems often lead to unexpected behaviors like time desynchronization and data loss. In Proxmox environments, restoring a VM snapshot reverts the guest system’s clock to the snapshot’s timestamp, disrupting services reliant on current time.

Forum discussions highlight solutions such as boot-time synchronization scripts. Similar challenges appear in shared databases and OS rollbacks, though details vary by platform. For mer information, se Moody Media.

This guide draws from community sources to address key troubleshooting scenarios.

Aspect	Details
Term	Rollback
Primary Contexts	VM restore, DB transactions, OS snapshots
Common Issue	Time desync, data loss in temps

Dominant Platforms	Proxmox, SQL, Fedora
VM Time Behavior	Reverts to snapshot timestamp
Potential Fix	@reboot cron job for host sync
Impact	TOTP authentication failures

In Proxmox, a VM rollback to a snapshot sets the guest time to the snapshot’s timestamp

Jag gillar att göra svåra saker enkla. Jag skriver guider som är lätta att skumma men också håller för fördjupning. Jag försöker vara saklig och tydlig med antaganden. Om du vill bidra med idéer eller rättelser, hör av dig.
