Freenas zvol7/31/2023 ![]() vbk file from the ZFS Snapshot directory \\NAS-01\Veeam\.zfs\snapshots\date\*.vbk.īut how to create this single. vbk file where Veeam daily commits the block changes of the HyperV VMs into, without any deduplication or compression, so ZFS can simply snapshot the block changes for each day. Our goal is it to archive the same behavior with our HyperV hosts using Veeam. In Proxmox you simply create a block level snapshot of a vm dataset and zfs-send it over to FreeNAS. Our current plan is to use ZFS snapshots to create a history of 2 years of backup files. Beside this we're still doing a daily backups on rotating drives. We're using the Standard Edition of Veeam.īefore we replaced our normal EXT4 NAS with a ZFS based FreeNAS we were simply doing a forward incremental backup to the SMB share. This is illustrated in the next article FreeNAS – Windows (CIFS) Shares on ZFS.We're currently running a HyperV cluster with two Hosts and a simple Proxmox machine in our environment. ![]() Having a periodic snapshots is like having a time machine – you can go back and restore the data to a previous state. The lifetime will be 2 weeks, it will run between 9:00 and 18:00 every hour from Monday to Friday: The next thing will be to set up a periodic snapshot for the ZFS volume. Let’s set the permissions for the new dataset from Storage -> View Volumes -> Change Permissions: The next screen-shot shows creation of a dataset named Backup: If you wish to divide up a ZFS volume’s data into different shares, create a dataset for each share. NOTE: if your goal is to share an entire ZFS volume, you don’t have to create datasets. A dataset is similar to a folder in that you can set permissions it is also similar to a filesystem in that you can set quotas and compression. In contrast ZFS datasets allow for more granularity when configuring which users have access to which data. This allows you to use a zvol as an iSCSI device extent for example. With the new ZFS volume in place you can create either ZFS Volume or ZFS Dataset.Ī zvol (ZFS volume) is a feature of ZFS that creates a device block over ZFS. The default interval between consecutive runs is 35 days. ZFS has a repair tool called “scrub” which examines and repairs Silent Corruption and other problems. This will also automatically create a ZFS Scrub for the volume. This will show a pop-up where you type the volume name, select the disk (in this case ada0), the file system type ( ZFS) and click Add Volume button: From the left navigation expand Storage -> Volumes and click on Volume Manager. The next step is to create the file system on the USB hard-disk. The newly created group is associated with the user (through the Members button).: The next two screen-shots show just that: These will be used later when setting the shares owner. I will start with creating a group ( HomeUsers) and user ( john). The goal is to create the file system (ZFS) and some Windows (CIFS) shares on top of it that will be available for data storage on my local network. ![]() I use an old laptop and 120GB USB hard-drive. I thought it was too complicated and I was afraid it will use up too much space because of the snapshots capability.įew days ago I installed the latest beta of FreeNAS 8 on a USB stick ( here how it is done) and decided to give a try to ZFS finally. I always was curious about ZFS but haven’t played with it until very recently.
