Re: [mongodb-user] Problem restoring from gzip archives: Failed: gzip: invalid header

[Gabriel Russell]

Rhys,

Can you show us the complete output of the mongorestore command?

If you use gzip to test the compressed stream like this, what do you get?

> gunzip -t /path/to/backup.gz

If that works, what happens if you do the uncompression external to the restore like so?

> gunzip -c /path/to/backup.gz | mongorestore --archive

Sincerely,

Gabriel

Hello,

I seem to be having an issue restoring gzip compressed backup files.

I am backing up like so...

mongodump --port "$PORT" --username "$MONGO_USER" --password "$MONGO_PWD" --gzip --archive="$BACKUP_DIR/$BACKUP_ARCHIVE";

I've been trying various restore string but the msot basic is...

mongorestore --gzip --archive /path/to/backup.gz

The backups have been taken from a 3.2.8 instance (with 2.2.8 tools). I have tried restores on 3.2.8 and 3.2.11 with the same result. 

The command...

file /path/to/backup.gz

Reports: gzip compressed data and I have been able to gunzip these files without any apparent issue.

Am I doing something wrong here with the backup or restores?

Cheers,

Rhys
