Hi Artem,
the restore command on the console is working fine with the backup created
by above code:
orientdb {test}> restore database
C:/Users/klinger/Documents/prototypes/conceptor-base/testbackup.zip
Restoring database database
C:/Users/klinger/Documents/prototypes/conceptor-base/testbackup.zip...
- Uncompressing file attribute.cpm...
- Uncompressing file attribute.pcl...
- Uncompressing file attributegroup.cpm...
[...]
Database restored in 0,86 seconds
orientdb {test}>
best regards,
chris
