Possible disadvantages of Duplicity

  • Complex Configuration
    Has a steep learning curve and complex configuration setup which may be challenging for non-technical users or those new to backup management.
  • Dependency on External Libraries
    Relies on several external libraries such as GnuPG and Python, which may complicate installation and maintenance.
  • Command Line Interface
    Lacks a graphical user interface (GUI), requiring users to operate through a command line, potentially limiting its usability for those unfamiliar with command-line operations.
  • Backup Speed
    Incremental backups can still be relatively slow, especially for large datasets or when using certain storage backends.
  • Restoration Time
    Restoring data can be time-consuming, particularly if multiple incremental backups need to be reassembled to recover the most recent version of files.
  • Limited Community Support
    Though it is open source, the community around Duplicity is smaller compared to more mainstream backup solutions, potentially leading to slower support and fewer third-party resources.

  • Which synchronization tool are you using together with the pCloud Crypto Folder?
    FreeFileSync messed up my pCloud database a couple times at first (causing disappearing files in the Crypto Folder, mirroring of the same files over and over again). Pcloud support provided an easy way to fix the database. To fix the root cause, one needs to exclude FreeFileSync's temporary files from the backup: pCloud Drive > Settings > Backup/Sync Exclusions, exclude sync.ffs_lock and *.ffs_tmp.
