Hi Guys, Recently, am testing the percona mongo backup tool, some questions as below: 1. Support for backup file encryption on local filesystem? As far as I know, It only support for AWS s3. 2. Support for backup on parallel ? How to specify the parallel number on backup command? 3. For PBM 2.0.3 , Support for physical backup by incremental ? Thanks Jason ---

Hi Jason, 1. PBM doesn’t support backup encryption. Physical backups work with [Data at Rest Encrypted databases](https://docs.percona.com/percona-server-for-mongodb/5.0/data-at-rest-encryption.html) 2. PBM runs backups sequentially, there is no support for parallel backups. Tbh, I’m not sure I fully understand what you mean by the backup on parallel. Can you provide a use case that needs parallel backups? 3. Yes, since v2.0.3 supports [incremental backups](https://docs.percona.com/percona-backup-mongodb/usage/incremental-backup.html). This feature is in technical preview though. Cheers! ---

Hello Andrew, Thanks for your professional suggestion! for the question 2: I mean if possible to issue the parameter like parallel or threads like below: pbm backup -type incremental --base parallel 4 ? pbm backup -type incremental --base threads 4 ? Seems no. So my question change to how to speed up the backup/restore performance ? Thanks Jason ---

Ah, I see. Backup uploads on S3/Azure storages are happening concurrently by default (for logical and physical backups, incremental included). As for the restores, we have the [changes](https://github.com/percona/percona-backup-mongodb/commit/85b566eb038481787b02f0c5b052dbf62e97a16c) in “main” that significantly speeds up physical restores from S3 type of storages. It is to be released in the next PBM version. Do you have issues with backups/restores speed? Can you elaborate more if so? What’s the storage type? Backups type (logical/physical)? Is it backup, restore or both? What’s the dataset size? How far is the storage from the cluster (the same region etc)? Cheers ---

Hi @Andrew_Pogrebnoi Thanks for your updates! Currently, No performance issue on backup/restore activities. For backup to local filesystem, Does the concurrently behaivor happened by default? Thanks Jason ---

No, unfortunately no concurrentcy for FS atm. ---
