Overview

Package backups provides information and interaction with backups in the OpenStack Block Storage service. A backup is a point in time copy of the data contained in an external storage volume, and can be controlled programmatically.

Example to List Backups 

listOpts := backups.ListOpts{
	VolumeID: "uuid",
}

allPages, err := backups.List(client, listOpts).AllPages(context.TODO())
if err != nil {
	panic(err)
}

allBackups, err := backups.ExtractBackups(allPages)
if err != nil {
	panic(err)
}

for _, backup := range allBackups {
	fmt.Println(backup)
}

Example to Create a Backup 

createOpts := backups.CreateOpts{
	VolumeID: "uuid",
	Name:     "my-backup",
}

backup, err := backups.Create(context.TODO(), client, createOpts).Extract()
if err != nil {
	panic(err)
}

fmt.Println(backup)

Example to Update a Backup 

updateOpts := backups.UpdateOpts{
	Name: "new-name",
}

backup, err := backups.Update(context.TODO(), client, "uuid", updateOpts).Extract()
if err != nil {
	panic(err)
}

fmt.Println(backup)

Example to Restore a Backup to a Volume 

options := backups.RestoreOpts{
	VolumeID: "1234",
	Name:     "vol-001",
}

restore, err := backups.RestoreFromBackup(context.TODO(), client, "uuid", options).Extract()
if err != nil {
	panic(err)
}

fmt.Println(restore)

Example to Delete a Backup 

err := backups.Delete(context.TODO(), client, "uuid").ExtractErr()
if err != nil {
	panic(err)
}

Example to Export a Backup 

export, err := backups.Export(context.TODO(), client, "uuid").Extract()
if err != nil {
	panic(err)
}

fmt.Println(export)
