System Requirements ------------------- 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 :ref:`datastore synchronization ` from other Proxmox Backup Server instances. 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) 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 :ref:`special device mirror `. * Redundant Multi-GBit/s network interface cards (NICs) Supported Web Browsers for Accessing the Web Interface ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To access the server's web-based user interface, we recommend using one of the following browsers: * Firefox, a release from the current year, or the latest Extended Support Release * Chrome, a release from the current year * Microsoft's currently supported version of Edge * Safari, a release from the current year
