Closed as program error.
Error description
Given the copy backups share the same location, the restored data could be from any of the PVCs in the same SLA. After a copy restore, the data will not be what is expected.
Local fix
The problem occurs when more than one PVCs is assigned to an SLA. Assigning a single PVC to a single SLA will prevent this problem. Increasing the snapshot retention period will ensure the data is available for recovery.
Problem summary
**************************************************************** * USERS AFFECTED: * * All 10.1.6 Spectrum Protect Plus users of the Kubernetes * * agent with an copy backup SLA where more than one PVC is * * assigned to the SLA. * **************************************************************** * PROBLEM DESCRIPTION: * * If there is more than one PV in the SLA, then during the * * copy backup operation, the data blocks from all PVs are * * copied to the same location in the vSnap server storage. The * * result is undetectable corruption of the backup data. No * * error is logged during backup. If a PV from the vSnap server * * is restored, the restore is successful but the restored PV * * is corrupted. * * * * The snapshots are not affected by this issue, and can be * * used to restore the PVs. * **************************************************************** * RECOMMENDATION: * * Apply fixing level when available. This problem is currently * * projected to be fixed in level IBM Spectrum Protect Plus * * levels 10.1.6 interim fix 1 and 10.1.7. Note that until the * * fixing level is available, this information is subject to * * change at the discretion of IBM. * ****************************************************************
Problem conclusion
The 10.1.6 interim fix1 will copy each PVC to a unique NFS mount location on the vSnap server.
