Unfortunately, times when you lose important notes are not so rare. This may be because of different reasons: deleting them accidentally, synchronization errors, etc. Previously, it was nearly impossible to get the data back, but now you can restore the missing note from the server backup. For free accounts, server backups are stored for 2 weeks. For Nimbus Pro accounts, backups are stored for 10 weeks. All Nimbus Note users enjoy the possibility of restoring notes from backup.
