Is it possible to generate "one-file" images from the deduplicated storage ?

[SRU]

Hi,
We are using the community subscription of VE and are evaluationg backup server without subscription.

We see a big benefit of the deduplication as it not only brings down the required storage size but also shortens sync to remote times.

However, "Authorities" require that we can present them all data of a single backup (VM / Container / phys.host) in a single big file as is created by vxdump.

Any chance to recreate that from the dedup storage, ideally with an option to output a stream to a tape library ?

Your adwise is welcome !

You can use the pbs backup client.

Using the FUSE option you can mount the raw block device.

What you do with it is up to you, you can read single files or stream the whole disk.

Thanks for the feedback. Could it be that this just works for hosts ?

 proxmox-backup-client mount vm/333/2021-01-15T11:15:03Z root.pxar /mnt/r --repository storage-bk
Error: manifest does not contain file 'root.pxar.didx'

In the web gui i can download a huge "drive*.fidx" file, what would be the equivalent of doing it using the backup client ?

proxmox-backup-client restore to actually restore to a raw image file, map if you just want to make it available as block device with each chunk being loaded on-demand from PBS when accessed.
