Backendless Pro - Unusual Backup Size Growth

Hello,

I’m using Backendless Pro, and my latest app backup has unexpectedly grown to over 20 GB, while previous ones were around 6 GB. The backup was generated as usual and the link sent via email.

Could you please help me understand:

  1. What might have caused this sudden size increase?
  2. What exactly is included in the backup?
  3. Are there folders (e.g., logs, file storage) that I should regularly clean up to avoid unnecessary growth?
  4. Are there best practices for managing storage and backup size in Backendless Pro?
  5. What´s the recommeded server size storage for the Backendless Pro? I currently have 100GB.

I’d appreciate your guidance to keep things optimized.
Highlight also that yesterday my server had 55Gb and today it has more than 70Gb…

Btw, we have an active support contract.

Please let me know if you need further info.

Thank you.

Best regards,
Manuel

Hello,

Regarding the sudden increase in your backup size, here are a few points to consider:

What might have caused the sudden size increase?

The most effective way to identify what changed is to take two backups — one from the current state and one from a previous state (if still available) — and compare their contents. This will help pinpoint where the additional data is coming from (e.g., files, database, logs, etc.).

What is included in a Backendless Pro backup?

A full backup typically includes:

  • Database (data tables and indexes)
  • File storage (all files in the /files directory)
  • System configuration
  • Log files

Are there folders (logs, file storage) that should be regularly cleaned?

Yes — large file growth often comes from:

  • Uploaded files in /files
  • Log files, especially if detailed logging is enabled and logs aren’t rotated or deleted
  • Custom directories where temporary data is stored

We recommend periodically reviewing the /files and /logs directories.

Best practices for managing storage and backup size:

  • Implement log rotation and cleanup policies
  • Monitor file uploads and storage usage
  • Regularly prune unused database records
  • Automate periodic storage reviews

Hope it helps!

Hello @stanislaw.grin,

Thank you for the prompt reply.

A few more questions?:
1.What we see in the first image is normal — almost 6 GB in backups within ui-builder?

2.Can all the .zip files shown in the second image be deleted?

3.When I generate a new ZIP file, does it include the previous ones inside it?
Maybe that would explain the exponential growth in the size of my recent ZIPs.

Thank you.

Can all the .zip files shown in the second image be deleted?

Root.zip could be deleted, it includes a zip of all files in your file system.

When I generate a new ZIP file, does it include the previous ones inside it?

If you zip a root - then yes.

Thank you.

Hello again,

It´s not about zipping a root (in file service, for example), I’m talking about the app “generate zip” option. Does this zip include previous ones (previous app generated zips)? I suspect it does.

Thank you.

Manuel

The zip includes everything your app includes. You can unzip the file and inspect its contents.

OK. Thank you.
