![]() Best of all, Mozy provides free backup service with 2 GB space with for free via MozyHome. If you delete a document and then run a backup, MozyHome assumes that you no longer need a backup copy of that document and marks the file to be removed.Mozy stores and saves a copy of data in a secure, remote location via secure upload for safekeeping, so that user can easily retrieve and recover back the data in the event of disaster. (We keep it for 30 days, just in case you change your mind.) After 30 days, the file is deleted from our servers and you are no longer able to get it back. It's strange that a company charging by the gigabyte would be so aggressive in deleting files. An option not to replicate deletions would seem to be in everyone's best interest.īackblaze competes with Mozy and recently re-commited to offering unlimited storage space. They too, delete backups of deleted files after 30 days. Same with Carbonite, another company offering unlimited storage for a fixed price. In fairness, there is no way for these companies to distinguish an intended file deletion from an accidental one or a file system error. But I can not recommend a backup scheme that does not offer an option to keep deleted files. The following is from their FAQ Does MozyHome support external drives? Mozy also lets you backup files that reside on an external hard drive, and that too comes with rules. If you have selected files from an external drive to be part of your regular backup and you unplug or turn off the drive while your backup is running, MozyHome detects that the files are gone and assumes that you no longer need them. Those files are then marked for deletion. After 30 days, the files are deleted from our servers and you are no longer able to get them back. However, if you reconnect the drive and run a back up, Mozy identifies the files, cancels the deletions and saves them in your backup set.īackblaze works best if you leave the external hard drive attached to your computer all the time. However, Backblaze will backup external USB and Firewire hard drives that are detached and re-attached as long as you remember to re-attach the hard drive at least once every 30 days. If the drive is detached for more than 30 days, Backblaze interprets this as data that has been permanently deleted and securely deletes the copy from the Backblaze datacenter. Then, there is the other side of the coin, where a customer wants to delete backed up files. For example, sensitive files might have been backed up accidentally. This is documented in an FAQ item How do I delete old backups? It turns out that you can't delete files held by Mozy on your behalf. Things get more complicated if a Mozy customer wants to save space. For example, an entry level user with one computer is now allowed to store up to 50 gigabytes of data for a fixed price. If they were storing 52 gigabytes back when it was all-you-can-eat, it's not hard to imagine that someone might want to delete some files to stay under the 50gb limit.Įasier said than done. You most likely don't need to delete anything because your quota is based on your current backup configuration. Your previous backups don't count against you, and they don't take up any of your quota. To illustrate further: Let's say you have a 1000 MB quota. If you back up 300 MB of photos, then your available quota goes down to 700 MB, and you've got 300 MB of photos on our servers. The next day, you change your mind and want to back up spreadsheets instead. So you tell MozyHome to only back up spreadsheets and not photos, and it goes ahead and backs up 100 MB of spreadsheets. So now, your available quota is 900 MB because you are only backing up 100 MB of spreadsheets now. However, if you want to restore those photos, you still can for 30 days until the file versions expire. Once any backup system is in place, monitoring it needs to be simple. Windows antivirus programs are a great example of this. ![]() They typically have an icon in the system tray that changes appearance to indicate a problem.
