Pika Backup

Refer: https://flathub.org/apps/org.gnome.World.PikaBackup
Video: https://www.youtube.com/watch?v=W30wzKVwCHo

Important! If you plan on using Pika Backup across devices, such as a Desktop and you also want to see those backup files on a laptop.

In PikaBackup, the archive prefix is a part of the naming convention used to identify backup archives. When you try to open or continue a backup on a different device, PikaBackup detects that the prefix is already in use by the backups from the original device. This is a safeguard to prevent conflicts and potential data corruption.

Here's what you should do:

  1. Understand the Archive Prefix: The archive prefix is a unique identifier for the backup series. It helps distinguish backups from different devices or different backup sets.

  2. Use a New Archive Prefix: When PikaBackup asks you to use a new archive prefix, it means you need to provide a new, unique identifier for the backup series on your laptop. This will ensure that the new backup set doesn't interfere with the existing backups from your desktop.

  3. Create a New Backup Set:

  • Open PikaBackup on your laptop.
  • Choose to create a new backup.
  • When prompted, enter a new archive prefix. This can be any string that you choose, such as "LaptopBackup_YYYYMMDD".
  • Proceed with the backup process.

  1. Avoid Overwriting Existing Backups: By using a new archive prefix, you ensure that the new backups created on your laptop won't overwrite or conflict with the backups from your desktop.

  2. Consistency Across Devices: If you need to access or restore data from the original backup on your laptop, ensure you are using the correct prefix and paths as used on the desktop.

By following these steps, you can safely manage your backups on multiple devices without risking data loss or corruption.

Quick solution:

With this kind of error, I usually start by raising the postBuffer size by:

git config --global http.postBuffer 524288000

(some comments below report having to double the value):

git config --global http.postBuffer 1048576000
