After putting very good zfs support (since then every my prox setup has been based on ) this  is (imho) next big big step So big congrats to the team !!! Now  I will shortly describe my usual cluster setups ... and will have one question about  fitting PBS into it - my cluster -  3 nodes ->  2 nodes are redundant VM hosts and 3rd node is quorum and BACKUP one ! Thank to  ZFS we actually have quasi inc backup (and the very very fast one -- snapshot repl etc etc )    This 3rd quorum/bck node has very big zfs 10 raid as backup repository ... But ... due to  zfs I can protect just one Prox host (standalone)  with other prox backup server very efficiently  and the most important benefits in scenarios above are: (imho) 1. very efficient backup (pve-zsync / storage (cluster) sync  etc ...) 2. Every backed-up VM is ready to run !  (on very that backup node ...  after snapshot cloning etc etc )   ... So this could be considered as DR solution also So since you are about to develop true and serious backup server (huge respect :) that can actually replace my 3rd backup node , the question would be:    Can PBS play quorum role ?    If yes, perfect ... I do not need 4th server , othervise  4th server (as such) is needed in smallest HA solution ... or ...   Can PBS "be" host also ? ... than I could install prox-qouroum VM ...  etc Thank you very much in advance BR Tonci /srdačan pozdrav / best regards / Tonči Stipičević, dipl. ing. elektr. /direktor / manager/** ** d.o.o. ltd. *podrška / upravljanje **IT*/ sustavima za male i srednje tvrtke/ /Small & Medium Business /*IT*//*support / management* Badalićeva 27 / 10000 Zagreb / Hrvatska – Croatia url: www.suma-informatika.hr mob: +385 91 1234003 fax: +385 1  5560007 On 10. 07. 2020. 13:56, pve-user-request@lists.proxmox.com wrote: > Send pve-user mailing list submissions to > pve-user@lists.proxmox.com > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-user > or, via email, send a message with subject or body 'help' to > pve-user-request@lists.proxmox.com > > You can reach the person managing the list at > pve-user-owner@lists.proxmox.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of pve-user digest..." > > > Today's Topics: > > 1.

It is specially optimized for the Proxmox Virtual Environment platform and allows you to backup and replicate your data securely. It provides easy management with a command line and web-based user interface, and is licensed under the GNU Affero General Public License v3 (GNU AGPL, v3). > > Proxmox Backup Server supports incremental backups, deduplication, compression and authenticated encryption. Using Rust https://www.rust-lang.org/ as implementation language guarantees high performance, low resource usage, and a safe, high quality code base. It features strong encryption done on the client side. Thus, it?s possible to backup data to not fully trusted targets. > > Main Features > > Support for Proxmox VE: > The Proxmox Virtual Environment is fully supported and you can easily backup virtual machines (supporting QEMU dirty bitmaps - https://www.qemu.org/docs/master/interop/bitmaps.html) and containers. > > Performance: > The whole software stack is written in Rust https://www.rust-lang.org/, to provide high speed and memory efficiency. > > Deduplication: > Periodic backups produce large amounts of duplicate data. The deduplication layer avoids redundancy and minimizes the used storage space. > > Incremental backups: > Changes between backups are typically low.

Make sure that you have at least pve-manager 6.2-9 installed. > > Q: What will happen with the existing Proxmox VE backup (vzdump)? > A: You can still use vzdump. The new backup is an additional but very powerful way to backup and restore your VMs and container. > > Q: Can I already backup my other Debian servers (file backup agent)? > A: Yes, just install the Proxmox Backup Client (https://pbs.proxmox.com/docs/installation.html#install-proxmox-backup-client-on-debian). > > Q: Are there already backup agents for other distributions? > A: Not packaged yet, but using a statically linked binary should work in most cases on modern Linux OS (work in progress). > > Q: Is there any recommended server hardware for the Proxmox Backup Server? > A: Use enterprise class server hardware with enough disks for the (big) ZFS pool holding your backup data. The Backup Server should be in the same datacenter as your Proxmox VE hosts. > > Q: Where can I get more information about coming feature updates? > A: Follow the announcement forum, pbs-devel mailing list https://lists.proxmox.com/cgi-bin/mailman/listinfo/pbs-devel, and subscribe to our newsletter https://www.proxmox.com/news. > > Please help us reaching the final release date by testing this beta and by providing feedback via https://forum.proxmox.com >
