Backup Error: Unknown Default Path for Creating New Journal File

April 16, 2025

Product Version

AhsayACB / AhsayOBM: 8.1 to 8.7

Operating System

All Platforms

Symptom

When performing a backup of any type, the following error message is received in the backup report:


[d] Failed to initialize RemoteBDB.Cloud. Error=[BlockDBConfig.readConfig] unknown default path for creating new journal file config: 0, caused by [RuntimeException] [BlockDBConfig. readConfig] unknown default path for creating new journal file config: 0

Cause

This issue can occurs if the temporary index files in the backup set's temp folder are corrupted, or the index files in the backup destination are corrupted.

Resolution

To resolve the issue, perform the following steps:

Ensure that the AhsayOBM / ACB client application is on the latest v8.7.0.0
First confirm if the issue maybe caused by corrupted index files in the temporary folder. Delete the index files in the backup set's temporary folder (e.g. E:\Users\user\temp\backupset_id\OBS@id\index\*).
Perform the backup again, the temporarily index files would be downloaded to the temp folder again. Continue to the next step only if the same backup error persists.
If the problem persist, revert to an earlier set of index files (e.g. from the last successful backup).
From the backup destination (e.g. AhsayCBS), browse to the "blocks" folder where the backup data are stored at:
%backup_destination%\%backupset_id%\blocks
(For Example: AhsayCBS Userhome Destination C:\Userhome\Username\1517279516004\blocks)
A separate folder is created for each backup job according to its start time (YYYY-MM-DD-hh-mm-ss), under the "blocks" folder. All files backed up by that job are stored in that particular folder.
Remove all index files (or move the files to another location) in the "blocks" folder:
- %backup_destination%\%backupset_id%\blocks\index.b2b.*.cgz
- %backup_destination%\%backupset_id%\blocks\index.xml.*.cgz
- %backup_destination%\%backupset_id%\blocks\index-s0*.cgz
Copy the index files from a previous backup job folder (snapshot (YYYY-MM-DD-hh-mm-ss) that you would like to revert to (e.g. from the last successful backup)), back to the "blocks" folder.
For Example
To revert the indexes to the backup on March 29, 2019 11:48:26, browse to
C:\UserHome\Username\1517279516004\blocks\2019-03-29-11-48-26
Copy
C:\UserHome\Username\1517279516004\blocks\2019-03-29-11-48-26\index.b2b.*.cgz C:\UserHome\Username\1517279516004\blocks\2019-03-29-11-48-26\index.xml.*.cgz C:\UserHome\Username\1517279516004\blocks\2019-03-29-11-48-26\index-s0*.cgz
To
C:\UserHome\Username\1517279516004\blocks\index.b2b.*.cgz/p> C:\UserHome\Username\1517279516004\blocks\index.xml.*.cgz/p> C:\UserHome\Username\1517279516004\blocks\index-s0*.cgz/p>
After the index files are reverted, data backup by the latest backup job (or sub-sequence job after the snapshot which you have reverted to) will not be displayed in the restore menu.
Perform the backup again to see if the problem persists.
