I’m trying to backup a Debian Stable PC to an NTFS directory on a Windows 10 v2004 server (detailed hardware configs at both links.)
The Debian PC has
dattobd installed and the datto snapshot method selected for the urbackup client. The backup source directory was set using
urbackupclientctl add-backupdir -d / -n root in the Debian terminal. Excluded files are
*/var/cache*; */mnt/*; */media/*; */dev/*; */snap/*; */proc/*; */sys/* in the server web UI.
The Windows PC has DOS names disabled as described here.
Both incremental and full file backups fail with the same error message in the Logs tab of the server web interface:
Errors 07/26/20 01:08 Writing directory metadata to "E:\UrBackup\DellOptiPlex390-1\200726-0102\.hashes\root\home\judah\.kde\cache-DellOptiPlex390-1" failed. Errors 07/26/20 01:09 Backup failed
The tail of the server-side live log is:
07/26/20 01:30 DEBUG Saved metadata of 40759 files and directories. 95% done... 07/26/20 01:30 INFO Waiting for file hashing and copying threads... 07/26/20 01:30 INFO Writing new file list... 07/26/20 01:30 INFO All metadata was present 07/26/20 01:30 DEBUG Syncing file system... 07/26/20 01:31 INFO Transferred 3.70542 GB - Average speed: 75.0027 MBit/s 07/26/20 01:31 DEBUG Script does not exist urbackup\post_full_filebackup.bat 07/26/20 01:31 INFO Time taken for backing up client DellOptiPlex390-1: 7m 53s 07/26/20 01:31 ERROR Backup failed 07/26/20 01:31 WARNING Exponential backoff: Waiting at least 3 days 13h 20m before next file backup
I’ve emailed the client and server debug logs.
Any idea what the problem may be?
