Error running backup

[ChrisDoernen]

Hi,

I get an error when the backup is running (stack trace below).

I don't know Go, but I believe the issue is the evaluation of this regex.

The output of running the mongodump command inside the container contains the following lines before the error is thrown:

basmongodump --gzip --host *** --port 27017 -u *** -p *** --db minds-q --authenticationDatabase admin
2023-05-26T10:03:36.578+0000    writing minds-q.fs.files to dump/minds-q/fs.files.bson.gz
2023-05-26T10:03:36.579+0000    writing minds-q.fs.chunks to dump/minds-q/fs.chunks.bson.gz
2023-05-26T10:03:36.586+0000    done dumping minds-q.fs.files (1 document)
2023-05-26T10:03:36.595+0000    done dumping minds-q.fs.chunks (1 document)

The collections are MongoDB collections to store files. Maybe the regex can't handle two dots in the collection name?

Help is much appreciated. This tool is really useful, I'd be very nice to use it!

Best

Chris

It seems like the problem is a dash in the database name. After renaming ("minds-q" to "mindsQ"), the backup did run.

Thanks for reporting it. I will find some time to fix it. Thanks!

[maxisam]
