What is the PBD file format?
Files with the .pbd extension are associated with EaseUS Todo Backup, a backup application developed by EaseUS (CHENGDU Yiwo Tech Development). .pbd files store backup copies of data such as folders, files, or disk partitions in a proprietary binary container that applies built-in compression and optional encryption. Backup copies can be used to restore deleted or corrupted data. Because the format is proprietary and undocumented, .pbd files can only be opened and restored using EaseUS Todo Backup - they are not manually editable and have no publicly documented file-header signature. Encrypted backups may only be restored on the system where the backup was originally created.
EaseUS Todo Backup is distributed under three license tiers, all of which create and read .pbd files:
- Free (free license) for non-commercial users - the basic version focused on simplicity; offers a limited set of features
- Home (paid license) for non-commercial users - enhanced version offering a wider range of features such as a backup scheduler, notifier, and transfer agent
- Workstation (paid license) for commercial users - the full-featured edition offering remote data and backup management among many features aimed at larger organizations
Related backup image formats include .GHO (Norton Ghost) and .TIB (Acronis True Image).
Security & safety
RISK: LOWA backup .pbd is passive data and safe in itself - it cannot execute. The real risks are practical: (1) it is useless without EaseUS Todo Backup and, if encrypted, without the password - losing either means losing the backup; (2) it may contain sensitive personal data from the imaged drive, so store and share it carefully. By contrast, a PowerBuilder .pbd IS executable code loaded by an app runtime - only run software whose .pbd libraries come from a trusted vendor.
Format details
in a nutshell- PowerBuilder Dynamic Library - Compiled bytecode/resource library (.pbd) generated by SAP/Sybase PowerBuilder for deployed PowerScript applications - runtime-only, not user-editable.
- PixelBender bytecode / generic project files - Various niche apps reuse .pbd for compiled or project data; rare and program-specific.
