We take backups of Dataminer everyday and noticed this error.
From Dataminer backup log:
2021-07-07 02:06:16|1 errors occurred during backup
2021-07-07 02:06:16|- An error occured when dumping the database. Error: [ERROR] Error on 'D:\ProgramData\Cassandra\SLDMADB\analytics_changepointalarmentries_v2-1753f500062b11eab224539de7960e3a\snapshots\dataminer-9d0ca2be-429a-4394-90da-3f91b5813f29\mb-5-big-Data.db': See InnerException for details. (More logging can be found in C:\Skyline DataMiner\logging\CassandraBackup.txt)
The file is overwritten everyday so couldn't capture any logs - but was wondering if anyone has an idea of the potential causes for this error?
Thanks,
Ryan
Hi Ryan
The screenshot turned out a bit small, but I believe the error code is -2147467259, which unfortunately is a generic error.
Based on the given error log, the backup seems to be having issues with a snapshot.
We've seen this in the past for several reasons, which could be due to insufficient disk space or that this file can't be accessed because it's being used by another process,... We would need to receive the CassandraBackup.txt to know the details.
What I would do is check if you have enough disk space. If the file is still opened in a program (using ProcExp = microsoft utilities) and perhaps a server reboot as well.
If you're using an antivirus software, be sure to whitelist all needed paths: https://community.dataminer.services/documentation/regarding-antivirus-software/
If this doesn't resolve your issue or if the issue returns, then I would advise to send a mail to techsupport with the logfiles (i.e. backup.log, CassandraBackup.txt and maybe all SL* txt files found in the Logging folder, all zipped).
Then a ticket will be created and this issue will get investigated.
Thank you for your answer! I will try those steps next time this occurs.
