@andrewreid Yes, I can't wait to share it with everybody.

@b-dietrich said in Externalised backup LTO:

Hi everyone,

I would like to know if it's possible to externalised backup on library tape with XOA ?

Is it in the roadmap for 2024 ?

I will let @olivierlambert on the backlog point. It is still planned, but there is a lot of ground work before :

• since tape can't be easily seek , so you'll have to write the backup at once no turning back to update a previously written block/metadata
• you'll have to build a catalog of tape<->backup to know which tape you'll have to use to restore, or rewrite. This is a huge change since XO don't use any database , the backup repositories are self contained : you can mount a backup repository to a new XO, and the backup will be listed . With tapes, you'll have to keep (and backup) the backup catalog. Yep , we'll need to backup the backups and ensure it's recoverable

That being said, the mirror backup feature as been built to pave the way to tape backup

For now the easiest way to do tape backup is to use full backup to a backup repository only used for this, and to mirror it to tapes. At our scale, priorities can also change if there is a big enough sponsor, that is ready to take a part of the financial load of this feature and gives us access to real world hardware and processes.

@CJ yes we have to fix the preview panel

the test with @dumarjo showed that there is still a bug during the import. I am still investigating it and will keep you informed, hopefully today or tomorrow

@ismo-conguairta said in VMware migration tool: we need your feedback!:

I have two different behaviour on two different XO instances. Each XO instance refers to a different pool (different hosts, same xcp-ng version). In both the instances I try to connect to the same Private Virtual Datacenter based on VMware/vSphere at OVH.

In the first one I get the following error message by using the web UI: "invalid parameters" (take a look at this logfile 2023-02-28T19_25_21.933Z - XO.txt )

In the second one, I get the following error message by using the web UI "404 Not Found https://<vsphere-ip>/folder/<vm-name>/<vm-name>.vmx?dsName=<datastore-name>"

By using the xo-cli I get the "404 Not Found" on both the instances.

Regarding the "404 Not Found", I want to point out that at OVH I have a VMware datacenter (with 2 hosts) and in order to access to the storage I need to specify the parameter dcPath=<datacenter-name>

So the right URL should be https://<vsphere-ip>/folder/<vm-name>/<vm-name>.vmx?dcPath=<datacenter-name>&dsName=<datastore-name>

Simply adding (in a static way) the dcPath specification on line :54 of esxi.mjs file makes it work.

I thought it was constant. I will look into the api to get it, and if not possible expose it in the UI

@Seclusion : noted I will look into theis error message, this one is a first for me

@brezlord mac address and uefi should works now

@rochemike patch done this morning

@rochemike great, that will be even easier

can you open a support ticket and open a support tunnel ? I will connect and patch your installation

@acomav you're up to date on your XOA

I pushed a new commit , fixing an async condition on the fix_xva_import_thin branch . Feel free to test on your XO from source.

@techjeff thanks for your effort, I found the problem

can you test this branch : fix_cr_healthcheck ? (git checkout fix_cr_healthcheck from xen-orchestra folder) it will be merged soon

hi @stilllearning @michmoor0725 @dumarjo we merged a fix in master.
For those who use a XOA, open a support tunnel and I will patch the installation

regards

Florent

@florent PR for bucket is here : https://github.com/vatesfr/xen-orchestra/pull/6757 it should be merged today and go live with the release on the end of he week

fbeauchamp opened this pull request in vatesfr/xen-orchestra

closed fix(xo-web): relax pattern for bucket #6757

@KPS that is a second bug
I will look into it this afternoon.
edit : confirmed, I'm working on it

@ronivay that's a great information. I can reproduce the comportment with xenserver 7.1 CU 2
Thank you

@parsedave Hi,

We worked on a branch that should fix it : https://github.com/vatesfr/xen-orchestra/pull/7583 It should be merged in master by the end of the week

Thanks for your report

closed fix(vmware-explorer): harden vmx parsing #7583

@Gheppy yes

at least if fixes import \o/

I am creatig card in the backlog to improve the import. Could you extract the ovf file of the windows ova ( rename it to tar and extract it) , and send it to me or post in in the forum ( it should not contains any confidential information )

@gasky @Gheppy

could you try this branch : fix_re_re_ova_export (PR is https://github.com/vatesfr/xen-orchestra/pull/7183/files ) ?

don't forget to do a yarn install before relaunching xo, since we updated a dependency

closed fix(xo-vmdk-to-vhd): improve compatibilty of ova with disk bigger than 8.2GB #7183

@olivierlambert yes, as soon as my branch is working as intended

For now I can generate a valid tar (with pax header) , but virtual box don't like it

@rtjdamen we found a clue with @Bastien-Nollet : there was a race condition between the timeframe allowed to enable CBT and the snapshot, leading to a snapshot taken before CBT , thus failing to compute correctly the list of changed block at the next backup

The fix is deployed, and we'll see this night. If everything goes well, this night will be a full, but the disks will keep CBT enabled. And the next night, we'll have delta

if everything is ok, it will be released in a second patch ( 5.100.2 )

@planedrop
with your setup, you'll have 15 real days of immutability at worst.
here is a little schema with Key backup ( full) and delta . A chain of backup is a key backup and it's delta descendants
mutable backups are noted with a point

K.d.dKdddddKd // in this case the first chain is not protected, because parts of the chain are mutable, but the 2 most recent
K.KdddddKddd // 2 more backups here we have the longest immutables chains
K.dddddKdddd // here is the critical part with the shortest imutable chains : only the last one
K.ddddKdddd //the protetectd chain gros

to ensure a usable immutability of n day, you must have a full backup retention of at least n, and a backup retention of at least 2xn

I am not really sure on the error message that the UI show on backblaze, but the backup will be merged and deleted as soon as possible, when the object lock is lifted.
you can trust backblaze on their object lock, and you cna check the real number of backup stored by looking at the restore tab of XO
