# Proxmox Backup Server

# System Anforderungen

<section id="bkmrk-we-recommend-using-h">We recommend using high quality server hardware when running Proxmox Backup in production. To further decrease the impact of a failed host, you can set up periodic, efficient, incremental [<span class="std std-ref">datastore synchronization</span>](https://pbs.proxmox.com/docs/managing-remotes.html#syncjobs) from other Proxmox Backup Server instances.

<section id="bkmrk-minimum-server-requi">### Minimum Server Requirements, for Evaluation

These minimum requirements are for evaluation purposes only and should not be used in production.

- CPU: 64bit (*x86-64* or *AMD64*), 2+ Cores
- Memory (RAM): 2 GB RAM
- Hard drive: more than 8GB of space.
- Network card (NIC)

</section><section id="bkmrk-recommended-server-s">### Recommended Server System Requirements

- CPU: Modern AMD or Intel 64-bit based CPU, with at least 4 cores
- Memory: minimum 4 GiB for the OS, filesystem cache and Proxmox Backup Server daemons. Add at least another GiB per TiB storage space.
- OS storage:
    
    
    - 32 GiB, or more, free storage space
    - Use a hardware RAID with battery protected write cache (*BBU*) or a redundant ZFS setup (ZFS is not compatible with a hardware RAID controller).
- Backup storage:
    
    
    - Prefer fast storage that delivers high IOPS for random IO workloads; use only enterprise SSDs for best results.
    - If HDDs are used: Using a metadata cache is highly recommended, for example, add a ZFS [<span class="std std-ref">special device mirror</span>](https://pbs.proxmox.com/docs/sysadmin.html#local-zfs-special-device).
- Redundant Multi-GBit/s network interface cards (NICs)
