Acronis Cyber Protect backup failed "error code 0x0190000B quota exceeded"

Not specified by the original author.

TL;DR

Error 0x0190000B means the backup plan's storage quota is exhausted: check the consumed quota in the management console by workload and storage location, then either raise the quota, free space by expiring old archives per retention, or move the workload to a location with headroom. New backups cannot start until space exists under the quota, so this is an entitlement and retention problem, not a job retry problem.

Acronis Cyber Protect backup failed "error code 0x0190000B quota exceeded"

Use this when

• The job or restore fails with this symptom: Acronis Cyber Protect backup failed with error code 0x0190000B quota exceeded.
• You are working on an Acronis Cyber Protect backup failing on quota and the failure repeats on the same target or schedule.
• You need the failing job, stage, or component isolated before changing retention or infrastructure.

Not for this skill when

• A quota that looks sufficient in the console while a different storage location's sub-quota is exhausted, where the fix is the location's limit.
• The error text names a different product, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Open the console's quota view and record usage and limit for the affected workload and storage location. Verify: the exhausted quota is identified precisely
2. Review retention on that location for archives that should have expired but did not. Verify: recoverable space is estimated
3. Raise the quota, expire archives per policy, or reassign the plan to a location with headroom. Verify: space exists under the applicable quota
4. Run the backup on demand and confirm it completes and the quota view reflects the new archive. Verify: backups resume under quota

The fix phrasing.

acronis 0x0190000b storage quota retention location

The location phrasing.

Compatibility: Acronis Cyber Protect quotas and cloud storage entitlements

Why it happens

Acronis enforces quota at the plan's storage location before the job writes anything, so an exhausted quota fails every run identically. The console aggregates can hide which location's limit is binding, which is why the check is per workload and per location rather than account-wide.

Edge cases / pitfalls

• Quota freed by retention applies on the platform's schedule; a backup retried immediately can still fail until the sweep runs.
• Growth trends predict this error weeks ahead; a quota report belongs in the monthly backup review.
