Whatever the operating system like Mountain Lion, Lion, Snow Leopard, etc you are using, you might meet the same problem of data loss. If you observe the reasons behind the data loss, you would get known that users always lost data due to hard drive failure, virus or malware attack and improper operations, which cause data loss on Mac OS X 10.8 Mountain Lion also. Then you would want to know if there are some efficient ways to avoid data loss.
Organize and classify your folders based on the data you handle, and give the appropriate names to the separate folder and files. Store any new information created or edited in your different designated folders, so as to prevent you to accidently delete the useful folders or files.
Normally all the files deleted by dragging them to Trash can be found in the Trash. However if you empty the Trash by clicking the “Empty” button at the top-right corner, the files will be permanently erased from the Trash. If the file size is larger than what the Trash can hold, unfortunately the deleted files cannot be retrieved from Trash also. So do not use Trash as a folder to store the information you may use later.
Use the up-to-date antivirus software to prevent your system from infecting with virus or malware, and keep the stability of your operating system to avoid it crash.
Make periodic backups of data by storing them in your removable storage devices. Do make sure that the backup works before you permanently delete them from your Mac Mountain Lion. Note: Scan the files with antivirus software to ensure that they haven’t be affected by virus already, before you make a copy.
Use a methodological manner to classify, index and archive your backup data, so that you are easy to retrieve the information when you require it anytime.
The above tips will largely extend against your data loss. But if you still lose the data, thankfully, the right Mac Mountain Lion Data Recovery Software from UFUSoft enables you to get back your missing data when you accidentally delete files, format, do improper operations or meet virus or malware attack on Mac OS X (including MAC OS X 10.4, Mac OS X 10.5 Leopard, 10.6 Snow Leopard, Mac OS X 10.7 Lion, Mac OS X 10.8 Mountain Lion, Mac OS X 10.9 Mavericks, Mac OS X 10.10 Yosemite, Mac OS X 10.11 EI Capitan, Mac OS X 10.12 Sierra) on iMac, MacBook, Mac Pro, MacBook Air, MacBook Pro, etc.
