Performance issues with OCI backup from snapshot and restore from backup copy

During OCI backup from snapshot operation the data is read from persistent disks that are attached to the Snapshot Manager. The speed of a backup job depends on the IOPS. Same issue appears with restore from backup copy jobs.

Workaround:

Add the following entry in the flexsnap.conf file in the NetBackup Snapshot Manager.

[oci]
vol_max_vpu_cnt_in_bfs_restore = 50

The value can be anything from the range 20 - 120, in multiples of 10.

Note the following:

  • For the backed up volumes NetBackup automatically increases the IOPS, when autotune is enabled. But higher IOPS might incur higher cost.

  • If you restore a VM with increased VPU, then after the restore, configure the VPU again to a normal value from the OCI console. You can re-configure the VPU value provided in flexsnap.conf file from the OCI console.
