Staging space configuration
vProtect node needs staging space available in
/vprotect_databy default. It is common to use PowerProtect DD for both the staging and backup destination. This will result in instant "store" processing, without the need to copy data from the staging space to the backup destinations. It is common to just attach an empty drive and mount it.
When using separate storage (usually local disks) for the staging space, please consider its requirements. Staging space size depends on the number and size of simultaneous backups - as a rule of a thumb make it approximately equal to the number of expected simultaneous backup threads multiplied by the size of your biggest VM.
In any case - make sure the staging space is always mounted in the
/vprotect_datafolder, and that the vprotect user is able to have full permissions to this file system.
You also can use a plain file system for staging space (and optionally for backup destination). Here are steps assuming you have a local (physical or virtual) disk.
- List all existing disks, and find your dedicated disk (let's say -
/dev/sdc):[[email protected] ~]# fdisk -l | grep devDisk /dev/sda: 32.2 GB, 32212254720 bytes, 62914560 sectors/dev/sda1 * 2048 1026047 512000 83 Linux/dev/sda2 1026048 62914559 30944256 8e Linux LVMDisk /dev/sdc: 500 GB, 17179869184 bytes, 33554432 sectorsDisk /dev/sdb: 21.5 GB, 21474836480 bytes, 41943040 sectorsDisk /dev/mapper/centos-root: 28.5 GB, 28462546944 bytes, 55590912 sectorsDisk /dev/mapper/centos-swap: 3221 MB, 3221225472 bytes, 6291456 sectors
- If you have a new clean disk prepare a filesystem on it:mkfs.xfs -K /dev/sdc
- Test mount your existing filesystem in the created directory:mount /dev/sdc /vprotect_data
- Set ownership to
vprotectuser on directory
/vprotect_data:chown vprotect:vprotect -R /vprotect_data
- Add a line to
/etc/fstabfile, to automatically mount new filesystem after reboot:/dev/sdc /vprotect_data xfs defaults 0 0
- Mountmount -a
- Confirm with
- Restart your
vprotect-nodeservice:systemctl restart vprotect-node
