VDP incremental backups ?

[DanieleFiore201]

Dear guys,

so far i'm not able to say if with standard VDP version it is possible to have incremental backups, do you know if is it possible ?
Cause i need to run full backup and many incremental, or will VDP consider further backups as incremental after a full backup ?

Many thanks in advance guys.

VDP does incremental backup by leveraging CBT(Change Block Tracking) feature of vmkernel.

The Backup/Restore VM task while backup is in progress shows either (F) or (I) in task details.

F-Full backup

I-Incremental backup

i'm executing the task but i do not see any F or I in the task detail

can u tell me where that exactly is ?

Hi,

I think you might be running 5.1 version, the UI is improved in 5.5

But however 5.1 do run incremental backups after a FULL backup.

Recalling again..it leverages CBT.

As i know VDP backup on a VM can turn into FULL in two cases

- if CBT tracking cannot be identified for some reason (a  rare case)

-if VM is migrated to another datastore.

Then on, the subsequent backups after FULL are always be incremental.

It is a drawback wrt to user interface in VDP 5.1 that it does not differentiate between FULL and Incremental backups but it actually does incremental backups internally.
