Daily Tape backup plan

Post by Friedrich95 » Mar 15, 2019 11:14 am

I have the following:
1- vSphere Cluster with 50 VMs backed up with a single Plan, daily increments and synthetic full on Friday.
2- 6 LTO-8 Tapes, Monday to Friday, and extra redundancy Tape for Friday.

I want to create a daily Tape plan to achieve the following:
1- Daily Tape Backups, i want to have the last Full and its increments on every Tape.
2- The "Friday-Tape-A" and "Friday-Tape-B" will be overwritten every 2 weeks.
So i can always have the previous Day and the previous Week on Tape.

What i did:
Screenshots below

https://ibb.co/r4NkzPM
https://ibb.co/tzkCTS8

Problem:
The first Tape in the chain was a success, the last Full and its increments were successfully copied.
The second Tape copied only the last incremental Backup and not he last Full and its increments.

Can anyone advice me, whether my goal is achievable?

Hello Friedrich95,

Just to make sure we are on the same page: you want to write entire chain to tape every day? Something like below:

Day 1
Disk: Full 1 + Inc 2 + Inc 3
Tape media 1 : Full 1 + Inc 2 + Inc 3

Day 2
Disk: Full 1 + Inc 2 + Inc 3 + Inc 4
Tape media 2: Full 1 + Inc 2 + Inc 3 + Inc 4

Correct?

I'm interested in this topic as well since we have a requirement to have a full month with daily increments as well. At present we have a file to tape job but it is tiresome to do a restore.

Does Veeam automatically check for Tape (Inventory) or i do have to do it manually each time?. when i insert a previously used Veeam Tape, it doesn't recognize it automatically, i have to do inventory to see the Tape online.

write entire chain to tape every day
Single media pool keeps track of all written data, so it's not possible to achieve your goal with current setup. From the top of my head you can do the following:

1. Create media pool per every day of the week (set the retention for 1 week to overwrite your tape media on a weekly basis)
2. Create backup to tape job per day of the week and point it to the corresponding media pool, run it on the desired day
3. You will get a setup: Backup to tape job Monday > Media Pool Monday
4. Every media pool will keep entire chain for the said day (similar to the state for the set day on disk)
5. Tape will be expired in one week, so it's going to be overwritten by the next job run

Makes sense?
i have to do inventory to see the Tape online.
Inventory is required to match the current tape with the information in Veeam B&R database.
