AWS Backup restore failed invalid parameter value for member account error

Not specified by the original author.

TL;DR

The member account parameter the restore passes is being rejected because the restore is running from the wrong account context or targeting an account that has not accepted the shared setup: restores of shared or copied recovery points must be executed with the correct account relationship, and the recovery point's vault access policy must allow the restoring account. Check which account owns the point, which account the restore runs as, and the identifiers passed, then run the restore from the proper side of the sharing relationship.

AWS Backup restore failed "invalid parameter value for member account" error

Use this when

• The job or restore fails with this symptom: AWS Backup restore failed with invalid parameter value for member account.
• You are working on an AWS Backup restore of a recovery point shared to or copied into a member account 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 restore failing because the account id in the request is malformed or belongs to a closed account, where the fix is the request data.
• The error text names a different product, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Record the recovery point's owning account, the account running the restore, and the account parameters in the request. Verify: the three account references are explicit
2. Check the vault's access policy for whether the restoring account is allowed to use this point. Verify: vault policy permission is confirmed or found missing
3. Align the restore to the documented sharing pattern: restore in the owning account, or copy the point into the member account first, per the setup in use. Verify: the restore path matches the sharing model
4. Re-run the restore with the corrected account context and confirm the resource is created in the target account. Verify: the restore completes in the right account

aws backup restore shared recovery point member account fix

The sharing phrasing.

aws backup cross account restore parameter error vault policy

The policy phrasing.

Compatibility: AWS Backup restores into organisation member accounts

Why it happens

Organisation sharing adds an account dimension to every restore parameter, and the API validates those parameters against the sharing relationship before doing any work. A restore written for a single-account setup passes plausible-looking values that the multi-account validation rejects outright.

Edge cases / pitfalls

• Copy-then-restore inside the member account avoids most sharing-parameter traps and leaves an auditable local point.
• Closed or suspended member accounts reject every parameter set; verify the account's standing early.

TL;DR

The destination vault name in the copy rule does not exist in the destination account, or the copy is looking in the wrong region: vaults are per account and per region, so a copy rule written before the vault was created, or pointing at a vault deleted later, fails every job with this error. Create or correct the destination vault in the exact account and region the rule names, and confirm the copy role can describe it, then re-run the copy.

AWS Backup job failed "backup vault does not exist" error in cross-account copy

Use this when

• The job or restore fails with this symptom: AWS Backup job failed with backup vault does not exist in a cross-account copy.
• You are working on an AWS Backup plan copying recovery points to another account 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 vault that exists but in a different region than the rule assumes, where the fix is the rule's destination rather than a new vault.
• The error text names a different product, stage, or root cause. Match the verbatim error first and use that skill.

Steps

1. Read the copy job's detail for the destination account, region, and vault name it attempted. Verify: the exact destination triple is known
2. In that account and region, list vaults and compare the name character by character with the rule's target. Verify: the vault's absence or name difference is confirmed
3. Create the vault with the intended encryption and access policy, or correct the rule to the existing vault's name. Verify: the rule's target now resolves
4. Check the copy role's permissions to describe and write to that vault across accounts. Verify: the role can act on the vault
5. Re-run a copy for one recovery point and confirm it lands in the destination vault. Verify: the copy completes and the point is listed

Variant phrasings

aws backup vault does not exist cross account copy

The verbatim phrasing.

aws backup copy job failed destination vault missing fix

The destination phrasing.

aws backup vault not found region account copy rule

The region phrasing.

Compatibility: AWS Backup cross-account copy jobs and vault management

Why it happens

Cross-account copies reference the destination vault by name across an account boundary the console view hides. A missing, renamed, or wrong-region vault therefore fails identically every run, and the error reads like a transient problem when it is pure configuration.

Edge cases / pitfalls

• Vault names are case-sensitive in some API paths; copy the name from the destination account, do not retype it.
• A vault created after the rule still needs the cross-account access policy updated in organisations that manage it centrally.

Fix this in Vanta and the connected AWS account by doing this first: in Vanta, open the AWS integration, re-accept the read-only cross-account role trust in the target account, confirm the external identifier matches the value Vanta shows, and rerun the sync for that one account. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

failed to connect AWS account

Use this when

• The operation fails with this exact problem: failed to connect AWS account.
• The same failure repeats on retry with unchanged inputs.
• An audit, review, or request is blocked until this item completes.

Not for this skill when

• The message is a platform outage notice or a general sign-in failure. Resolve that first, then return here if this problem remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in Vanta and the connected AWS account, and copy the full message plus the item, account, or request involved into the run notes. Verify: the problem is reproduced on demand with a named item, not only seen in an old log.
2. Apply the specific fix for this problem: in Vanta, open the AWS integration, re-accept the read-only cross-account role trust in the target account, confirm the external identifier matches the value Vanta shows, and rerun the sync for that one account. Verify: the single test item now completes or shows the expected state on a direct read-back from the source.
3. Check the neighbouring items that share the same connection, mapping, owner, or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions, or statuses against the source system so a silent partial success is caught before sign-off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the operation completes and the original problem does not appear.
6. Record the fix, the triggering input, and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied, and the evidence of success.

Why it happens

The cross-account trust or external identifier drifted after a role change in the AWS account, so Vanta can no longer assume the role and every evidence test for that account goes stale.

Variant phrasings

Vanta evidence sync error failed to connect AWS account audit evidence missing

The verbatim form searchers paste from the console or ticket. Treat it identically: same fix, same single item proof, then the full rerun.

How to fix this failure in practice

The how-to phrasing for the same failure. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Troubleshooting the symptom-first form

The phrasing used when the console hides the full message. Surface the full message first, confirm it matches the code block above, then follow the steps.

Compatibility: Vanta at current versions, plus the source systems the query names; no extra tooling beyond the platform console or API access needed to verify counts.
