I need help restoring a backup made with the complementary dump command.
Previously I was able to save data from a Ubuntu 20.04.5 install with the dump command as binary file on an external USB drive. I tested the backup and I'm able to read it but not to restore it. Meanwhile I moved forwards and reinstalled the OS on same hardware. I chose to wipe all data on the NVMe SSD first.
I used the command restore with flags operating from a live (systemrescue9.05) medium in 'interactive' mode, reading from the binary file using: restore -iaN -f /mnt/save/binary-file. I invoked the command from root '/' of the live medium.
Path to binary file mentioned, path to root from device where data should become restored: '/mnt/source/'. The binary file contains my saved /home directory.
Here sharing output of what I tried at a terminal:
- remark I chose to access a small directory '/home/alexandre/PDF' from the binary file,
- remark I tried several times to extract, leading to different errors...
{user@pcname}# restore -iaN -f /mnt/save/binary-file
restore > add /home/alexandre/PDF
restore > extract
restore: <name unknown>: ftruncate: Invalid argument
restore > extract
