[SOLVED] Deduplication Factor Explanation

[Donovan Hoare]

Hi All.
I have searched and googled, I would like to know what the deduplication factor shown on the summary means.
My deduplication factor on a data store is currently 10.77

I have no idea if that's good or bad.
And does that mean 10.77% of data is deduplicated?

If someone could please maybe explain it would be helpful
This particular datastore has 22 windows vm's in it

Thanks for any help

deduplication_factor = original_data_size/stored_data_size

It means that if there was no deduplication you'd need 10.77 times as much space with the same backups as you do now.
As example, if you would use 50 GiB of storage now, you'd use 500 GiB without duplication.

A factor >>1 means always there was space saved by deduplication.

As thread creator you can use the Edit Thread button at the top right, there you can set the "Solved" prefix.

I think something changed and after X days threads and posts become uneditable. At least I'm also often not able to edit older threads or posts.

@fabian edited for you, and I'll look into the permission issue.

One example if it might help you.
I can edit this new thread ("Edit Thread" button is there): https://forum.proxmox.com/threads/best-way-to-setup-swap-partition.116781/
But I can't edit this old thread ("Edit Thread" button missing): https://forum.proxmox.com/threads/feature-request-advanced-restore-options-in-gui.109707/

Already got it, there's a time limit setting now for normal users by default, was set to 7 days. For now, I upped it to 5 weeks (there are some spammer sleeper accounts that make edits after a while to sneak in junk links, so juft for that it should be worth it; and 5 weeks is quite a bit of time and should cover most threads/post just fine).

 

[Dunuin]

1 weeks was really a bit short.
Is it maybe possible to give some additional rights for users who have proven to not be spammers? For example additional edit timespan after 25 posts or something like that? I would guess spammers wouldn't invest so much time in writing real on topic posts, just to sneak in some links later.

And maybe there should be a "I'm a bot" category. The bots writing here, really like to tag threads with the "Tutorial" category
