Full Backup - Unstructure Data Backup - SMB

[louis417asdo]

Hi,

I want to use File Backup via Veeam to perform a weekly full backup on Sat, and daily incremental backup from Sun to Thu.
I know it can be done on VM backup, but how about SMB File Backup?
I have read all related document, but it seems no related information...

I know the file backup is like below:
Day 1: File 1 (version1)
Day 2: File 1 (version2)
.
.
.
Day 31: File 1 (version31)

It looks similar to forever incremental backup in VM backup...
What happened Day 15 File 1 (version15) is lost of corrupted? All of my file backup are damaged??

Hello louis417asdo,

NAS backup job is forever forward incremental but currently does not provide an option for periodic full backups. You can configure the desired schedule but after first full backup you will have incrementals.

What happened Day 15 File 1 (version15) is lost of corrupted? All of my file backup are damaged??

New incremental backup will be created based on information from pervious day i.e. 14. Additionally, NAS backup has health check and repair functionality which allows to heal the backup and repair the backup data which was partially corrupted.

Thank you Dima,

Can you explain more in here??

I have 31 days checkpoint, if day 15 is corrupted, is all backup point after day 15 are gone??

If restore point is missing or corrupted we will build the new incremental based on the history stored in previous non corrupted restore point:

Code: Select all

Day 1 restore point: File 1 (version1) File 2 (version1) File 3 (version1)
...
Day 13 restore point: File 1 (version13) File 2 (version13) File 3 (version13)
Day 14 restore point: File 1 (version14) File 2 (version13 - unchanged, reference to a previous restore point 13) File 3 (version13 - unchanged, reference to a previous restore point 13)
Day 15 restore point: File 1 (version15) File 2 (version13 - unchanged, reference to a previous restore point 13) File 3 (version14)
...
Day 16: restore point 15 is corrupted, File 1 (version16) appears on disk, others remain unchanged
Day 16 restore point: File 1 (version16), File 2 (version13 - unchanged, reference to a previous restore point 13) File 3 (unchanged, reference to a previous restore point 15)

I have 31 days checkpoint, if day 15 is corrupted, is all backup point after day 15 are gone??

Nope, we can heal the existing restore point (both metadata and data) to allow restore of the content which was not corrupted. Simply put - you will loose only the data that sits on the corrupted disk sectors. By the way, to avoid that you can use backup copy or copy to archive repository both will allow you to create a mirror of your backup on primary repository.

Appreciate Dima for detail explain!

I suggest Veeam can consider to add Full Backup feature like VM in future~!
