What is the maximum number of storage that I can create?

inSync does not set restrictions on the number of storage that you can create. However, you can get an estimate of how much storage you might need by using the inSync Deduplication Savings Calculator available at

Does Druva recommend the number of storage?

Can I create the Database folder on NAS? 

The Database folder contains metadata about backup data. inSync server needs this metadata to identify backup data. inSync does not support the creation of the Database folder on a shared drive or Network-access storage (NAS). Always create this folder on a local drive, separated from networks.

What is the minimum disk space for Data, Database, and Database log?

We recommend the disk space for Database and Database log folders to be at least 5% of the Data folder size. However, the size of Database and Database log must be at least 8 GB. Also, the Database and Database log folders require a minimum free space of 4 GB. The minimum disk space for Data folder is 1 GB. 

How many data volumes can I add to a storage?

You can add only one data volume to an existing storage. 

What happens if I change a user's storage?

When you change a user's storage, user data will be backed up to the new storage. Snapshots on the old storage are retained and compacted following the retention policy. However, the user can restore data from any snapshot, even those available on the old storage.

Do users come to know if their storage changes? 

No. Users will not know that their storage has changed. 

Do users start backing data to the new storage immediately?

Yes, users can start data backup as soon as they move to the new storage. 

If I change a user's storage,is the first backup a full backup? 

Yes. The first backup is a full backup. Thereafter, all backups will be incremental in nature. 

Are old snapshots retained on the earlier storage?

For a while, yes. The time for which snapshots are retained is determined by the retention policy. At the end of the retention policy, these snapshots are compacted following the compaction policy that you adopted. 

Can users restore data from any snapshot?

Yes, users can restore data from any snapshot, including the ones residing on the old storage. 

Does the flexible storage mapping feature have limitations? 

To know the limitations of this feature, read Changing storage assigned to a user.
