This method requires stopping the Acronis Storage Node Service.
Both methods use the same principle: if the storage node does not find the database, it creates the
database from scratch. This process length depends on the datastore size and disk I/O speed. On
average, 1 TB of the datastore requires 3 hours. The next section describes how to find the datastore
file.
How to find the datastore file
Use the vault path displayed on the vault page:
If a local path is displayed, this path is on the machine with the storage node.
The datastore file has either the *.ds.0 or the *.ds.1 extension. Two files with these extensions are in
the vault while compacting is in progress. If you find two files, use the sum of both file sizes to
estimate the upgrade time.
Re-attaching the managed vault
This method requires that you know the location of the deduplication database files.
How to find the deduplication database files
Use the deduplication database path displayed on the vault page:
The deduplication database files have the *.db3, *.db3-wal, and *.db3-shm extensions.
Re-attaching the vault
The procedure varies slightly, depending on where the database files are stored.
If the vault is encrypted, you must provide the encryption password when re-attaching the vault.
Deduplication database and datastore are in different folders
1. Note the folder where the old deduplication database files are stored (to be able to roll back the
changes).
2. Detach the managed vault.
3. Attach the managed vault. When attaching, specify another folder where the new deduplication
database is to be created.
