OmniDrive Backup FAQ

Q: Can I back up only changed files?

A: Yes, we support incremental backup by default, i.e. only new and modified files will be uploaded after the initial backup.

You can also use Block level backup for files that consist of blocks (e.g. Outlook pst-files).


Q: What ports (TCP and UDP) does your software need?

A: We use standard TCP ports 80, 443 and 8119.


Q: What protocol are we using on transmission?

A: It is always HTTPS.


Q: How much memory does the OmniDrive backup process consumes on a client PC?

A: The default is to use 300MB for uploading. The memory usage depends on the selected chunk size (Tools | Options | Advanced): the larger the size is, the more memory is used. If chunk size is more than 300MB, we use disk space (temp folder) in order to avoid memory overload.


Q: What is the compression ratio?

A: We use GZIP to compress the data. The effective compression ratio depends mostly on the content/size/type/amount of files and may vary from one environment to another.


Q: How does master password work?

A: The master password helps you to protect your backup from unauthorized access. Only those who know the master password can start the OmniDrive Backup. The Master password is optional and off by default.


Q: How does OmniDrive Backup recognize modified files?

A: We use timestamps to identify modified files


Q: How to restore files/proceed with backup on another computer?

A: Add the same OmniDrive cloud account and choose the same prefix in advanced settings. By default the prefix is your old computer name. Specify the same encryption password as you used to back up the files. If you don’t see the files which is unlikely, try to synchronize the database, go to Tools | Options | Repository and click Synchronize Repository.


Q: Why does the program not appear to start when I start the computer?

A: OmniDrive operates as a Windows Service. There is no need for the console to run when the computer starts and actually it doesn’t have to be run at all. You only need it for configuration and restore. The service will do the entire job.


Q: Can I protect my data with a password?

A: Yes, we support the multiple industry standard encryption algorithms including AES 128-256 bit and it does encrypt/decrypt on the fly. You can set it up in the backup plan wizard.


Q: Is there a way to decrypt OmniDrive backups independent of the OmniDrive interface?

A: There is no way to decrypt the files outside of OmniDrive Backup because encryption metadata (encryption algorithm, key-size, etc.) is stored in our own format.


Q: Can I back up files being in use with OmniDrive Backup?

A: Yes, OmniDrive Backup supports backup of files being in use by default. For this purpose OmniDrive Backup uses the Volume Shadow Copy Service (VSS). The Volume Shadow Copy Service is an implemented Windows service. It allows taking snapshots of data being in use or located on a locked volume. The Volume Shadow Copy Service doesn’t work for network shares, mapped network drives or drives with the FAT32 file system. When OmniDrive Backup detects a file being in use it automatically creates a VSS snapshot of such file and works with it instead.


Q: What does “Force using VSS”​ option​ mean?

A: “Force VSS”​option ​is designed to prevent locking files by OmniDrive​ backup client ​to allow other software simultaneous access to those files.



Q: If I stop a backup plan, is the data that has already been uploaded, lost and when it is restarted, does the process start again from zero?

A: Any restart continues the backup process from the point where it left off.


Q: Do you support Mac and Linux?

A: Yes, we support Mac and Linux for cloud and local storage.


Q: How often should I run Full backup if I use Block-level backup?

A: You can schedule “Full backups” depending on how often your files are changed. If you have multiple modifications a day, you can schedule “full backup” once in 2 days.


Q: Will backup start if the computer is sleeping?

A: No, but you can keep “Run missed backups immediately when computer starts up” checked on the Schedule step


Q21: Can I change CPU utilization?

A: You can specify the priority for backup plans under Tools | Options | Advanced: Process priority


Q: Can I backup and restore my system as an image?

A: Yes provided your version supports images.


Q: What is a difference between Bare Metal Backup and Image Based Backup?

A: Bare metal is a Windows image backup. It’s supported for Windows 2008R2 and later and has many limitations. We recommend using our own Image Based Backup technology with advanced functionality.


Q: Can I recover a single file from image based backups?

A: Yes, starting from version 4.3. you can recover individual files from image based backups without downloading the whole image.


Q: Can I create a bootable USB drive?

A: Yes!

A: Yes, learn more how to backup and restore MS SQL.


Q: Do you support backup for MS Exchange?

A: Yes, learn more how to backup and restore MS Exchange.


Q: Can I check the consistency of my backups?

A: Yes, consistency check option allows you to check that all files actually exist on the destination. The consistency check updates the local repository records (local index database located in the user profile) and makes it up to date to the cloud storage.​


Q: Can I backup and restore NTFS permissions?

A: Yes, starting from 4.5. version, you can backup and restore NTFS permissions.
