63288: Acronis Cyber Infrastructure Backup Gateway: how to reconfigure ABGW to use another NFS export to store archives

use Google Translate

Scenario

You use Acronis Backup 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.

Solution

Downtime is expected.
  1. Stop Acronis Backup Gateway by issuing:
    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 contents of /mnt/vstorage/vols/acronis-backup/storage to the new NFS share.

    You need to move all contents of the old NFS export; partial migration is not supported.
  3. Unmount current share by issuing:
    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:
    1. Open the config file:
      vi /etc/vstorage/abgw.config
    2. Find parameters storage.nfs.host and storage.nfs.export
    3. Press i to enter editing mode.
    4. Specify new values.
    5. Press Esc to exit editing mode.
    6. To exit the editor and save changes, type:
      :wq
  5. Mount the new share by:
    vstorage-abgw-ctl nfs --mount
  6. Verify that /mnt/vstorage/vols/acronis-backup/storage contains customers' directories.
  7. Start Acronis Backup Gateway by:
    systemctl start vstorage-abgw

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