### Permanent deletion of objects in S3 and compatible storages
By default, when using S3 compatible storages, `vmbackup` and `vmbackupmanager` will use the basic delete operation,
which will delete current version of the object only.
In order to enforce removing all versions of an object when object is deleted, you need to use `-deleteAllObjectVersions` flag.
Using this flag will enforce listing all versions of an object and deleting them one by one.
`vmbackup` and [vmbackupmanager](https://docs.victoriametrics.com/vmbackupmanager.html) use standard delete operation
for S3-compatible object storage when pefrorming [incremental backups](#incremental-backups).
This operation removes only the current version of the object. This works OK in most cases.
Sometimes it is needed to remove all the versions of an object. In this case pass `-deleteAllObjectVersions` command-line flag to `vmbackup`.
Alternatively, it is possible to use object storage lifecycle rules to remove non-current versions of objects automatically.
Refer to the respective documentation for your object storage provider for more details.
