OST MetaData

3. What is MetaData? It is not delivered via stsp_write_image_meta()
Provides attributes of NBU client objects within a backup stream in varying degrees of detail, depending on the backup method.
Use this information as hints for further object analysis in your plugin or storage server
Delivered via sts_stat_t in the stsp_write_image() interface
int stsp_write_image(
stsp_image_handle_t image_handle,
sts_stat_t *reserved,
void *buf,
sts_uint64_t len,
sts_uint64_t offset,
sts_uint64_t *byteswritten);
sts_stat_t need not be persisted--it is not restored with the image.
In use since NetBackup 6.0, OST vendor feature beginning 6.5.4
