4.3 - Storage for Backups ?

[fpausp]

I installed a testserver (4.3) and need to configure a storage with lets say ~1TB, just for backups...

Where and how can I do that ?


Here is my Partition layout:

Filesystem      Size  Used Avail Use% Mounted on
udev             10M     0   10M   0% /dev
tmpfs            13G  9.1M   13G   1% /run
/dev/dm-0       237G   31G  194G  14% /
tmpfs            32G   43M   32G   1% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs            32G     0   32G   0% /sys/fs/cgroup
/dev/fuse        30M   20K   30M   1% /etc/pve

If you only have one disk, just use snapshots, because a backup on the same disk is not a backup.

If you still want to use the backup button, just use the pve-data for that. Please post the output of pvesm status.

I think I misinterpreted the output of lsblk. Just create a new volume and mount it like it is described here:
