Last update: 21-02-2023


You use Acronis Cyber Cloud with NFS backend connected through Backup Gateway. You want to migrate the NFS shares to a new server and need to reconfigure ABGW to use the new NFS export.


Downtime is expected.

1. Stop Acronis Backup Gateway service by issuing the following command:

# systemctl stop vstorage-abgw

Performing further steps without stopping vstorage-abgw will lead to corruption of archives!

2. Move the data between NFS boxes/shares. For example, copy content of old NFS share to the new NFS share.

You need to move all contents of the old NFS export; partial migration is not supported.

3. Ensure that current share is unmounted with the following command:

# vstorage-abgw-ctl nfs --umount

4. In /etc/vstorage/abgw.config set the new NFS server address and share name. For example, using the vi editor:

a. Open the configuration file:

# vi /etc/vstorage/abgw.config

b. Find parameters storage.nfs.host and storage.nfs.export

c. Press i to enter editing mode.

d. Specify new values.

e. Press Esc to exit editing mode.

f. Type :wq to exit the editor and save changes.

5. Mount the new share with the following command:

# vstorage-abgw-ctl nfs --mount

6. Verify that /mnt/vstorage/vols/acronis-backup/storage/ directory (default mountpoint path) contains customer tenant directories:

# ls -alh /mnt/vstorage/vols/acronis-backup/storage/

7. Start Acronis Backup Gateway service:

# systemctl start vstorage-abgw

Now you can continue backing up; backups will be saved on the new NFS share.
