One crucial aspect of data security in cloud storage pertains to the handling of file deletions. Specifically, when a file (referred to as an ‘object’ in the context of object storage services like Cloud Synergy) is deleted, it’s important to understand the procedures that come into play and how the disk space previously occupied by the deleted file is repurposed for storing other files. File deletions can occur at various levels, such as when you delete an individual file or when you delete a parent folder, bucket, or account.

Here’s what happens when a file is deleted on Cloud Synergy:

1. The file is internally marked as ‘object deleted,’ effectively rendering it inaccessible via storage application.

2. Metadata associated with the deleted file is removed from the Cloud Synergy database.

3. The content of the deleted file is wiped from the Cloud Synergy storage disk, and the space previously occupied by the file undergoes a secure overwrite process called ‘compaction.’ Once this secure compaction process is completed, the disk space becomes available for storing other files.

It’s important to note that once a file, folder or account is deleted on Cloud Synergy via storage application, Cloud Synergy Support cannot recover the deleted content. The content is permanently erased from Cloud Synergy at this point. To mitigate concerns related to accidental or unintended deletions, consider using additional bucket with replication.

On a related note, in the event of a failure in a Cloud Synergy storage disk containing customer content, and the subsequent need for disk replacement, Cloud Synergy adheres to a similar secure process to ensure that the data on the failed disk remains inaccessible and unrecoverable. Cloud Synergy’s erasure coding process guarantees that the disk replacement procedure is transparent and non-disruptive to customers, ensuring the preservation of file integrity and access.
