View source for Company:Comparison of online backup services

{{short description|None}}

This is a '''comparison of online backup services'''.

Online backup is a special kind of online storage service; however, various products that are designed for file storage may not have features or characteristics that others designed for backup have. Online Backup usually requires a backup client program. A browser-only online storage service is usually not considered a valid online backup service.

Online folder sync services can be used for backup purposes. However, some Online Folder Sync services may not provide a safe Online Backup. If a file is accidentally locally corrupted or deleted, it depends on the versioning features of a Folder Sync service, whether this file will still be retrievable.

*{{note|1|1}}'''[[Software:Microsoft Windows|Windows]]/[[Software:Linux|Linux]]/[[Software:Mac OS X|Mac]]/[[Software:IOS|iOS]]/[[Software:Android (operating system)|Android]]/[[Engineering:BlackBerry|BlackBerry]]''': Supported operating systems for thick client (native binary application), which provide background data transmission and setting services.
*{{note|2|2}}'''Zero knowledge''':  The service provider has no knowledge of the user's encryption key, ensuring privacy of the backup data.<ref>{{Cite web|url=https://www.economist.com/babbage/2011/05/18/keys-to-the-cloud-castle|title=Keys to the cloud castle|via=The Economist}}</ref><ref>[http://evilrouters.net/2011/04/20/why-i-use-jungle-disk-and-tarsnap/ Why I Use Jungle Disk and Tarsnap — Evil Routers]</ref><ref>{{Cite web|url=https://www.theguardian.com/technology/2014/jul/17/edward-snowden-dropbox-privacy-spideroak|title=Snowden: Dropbox is hostile to privacy, unlike 'zero knowledge' Spideroak|first=Jemima|last=Kiss|date=July 17, 2014|via=The Guardian}}</ref>
*{{note|3|3}}'''Secure Key Management''': If yes, the user holds and controls the encryption key. If no, the service provider holds and controls the encryption key.
*{{note|4|4}} Payment options/plans:
**'''Limited MB plan''': Pay per computer. Additional fee for storage over a threshold.
**'''Unlimited MB plan''': Pay per computer. Storage per computer is unlimited.
**'''$/MB plan''': Pay per unit of storage, but unlimited computers may share that storage.
*{{note|5|5}}'''Cloud hosted Net Drive''': Cloud can serve storage over [[WebDAV]], [[Server Message Block|SMB]]/CIFS, NFS, [[Apple Filing Protocol|AFP]] or other [[Network-attached storage|NAS]] protocol, allowing files to be streamed from the cloud. A change made to the cloud is immediately accessible to applications on all clients without needing to pre-download (sync) the file in full.
*{{note|7|7}}'''Sync''': [[File synchronization|Synchronization]] between computers, and/or mobile devices (PDA, MDA,...)
*{{note|8|8}}'''Public Internet file hosting'''
*{{note|9|9}}'''Restore via physical media'''
*{{note|10|10}}'''Server location''': Countries where physical servers are located.  Where the data will be located.
*{{note|11|11}} Still in Beta version
*{{note|12|12}} Whether the desktop client (if available) can detect and upload changes without scanning all files.
*{{note|13|13}} Many backup services offer a limited free plan, often for personal use. Often it is possible to increase the free backup limit through coupons, referrals, or other means that are not included in this column. This column also does not include free trials that are only available for a limited period of time.
*{{note|14|14}} '''External hard drive support''': Can refer to an alternate backup destination or whether the service can back up external drives.
*{{note|15|15}} Hybrid Online Backup works by storing data to local disk so that the backup can be captured at high speed, and then either the backup software or a D2D2C (Disk to Disk to Cloud) appliance encrypts and transmits data to a service provider. Recent backups are retained locally, to speed data recovery operations.
*{{note|16|16}} '''Unlimited BW''': If bandwidth capping or limits are used on accounts.

===Other features and limitations===
Other notable limitations or features.
; Baidu Cloud: Must be registered by verified phone first.
; Box		: Performance degrades after 10,000 files in sync folder. Technical limit of 40,000 files in sync folder. Does not sync .tmp files, Outlook PST files, hidden files (hidden folders are synced), or any file or folder with \/*?":<>| in the name.<ref>{{Cite web|url=https://support.box.com/hc/en-us/articles/200521078-Box-Sync-3-x-Behavior-Limitations-and-Recommendations|title=Box Sync 3.X Behavior, Limitations, And Recommendations}}</ref>
; CloudJuncxion : Decentralized fragment-and-disperse storage across a collection of heterogeneous clouds for maximal security. Supports a Virtual Private Cloud model for complete control by the enterprise customer. Supports Sync Groups for greater control over synchronization of files across multiple devices. 
; Dropbox: Performance degrades with more than 300,000 files in sync folder. This is a soft limit.<ref>{{Cite web|url=https://help.dropbox.com/storage-space/file-storage-limit|title=How many files can I store in my Dropbox account?|website=help.dropbox.com}}</ref>	
; Google Drive : All account types are limited to 750 GB upload bandwidth per day. <ref>{{cite web|url=https://support.google.com/a/users/answer/7338880?hl=en#uploads|title=Upload limits in shared drives.|publisher=Google Inc.|access-date=2021-07-07}}</ref> Enterprise accounts are now limited to 5 TB per paid user on the account whereas prior to May 2023 only a single user was required for the advertised unlimited storage. Once 5 users are on an Enterprise account, more storage can be requested in 25 TB allotments once every 90 days, but extra storage is not guaranteed. The extra allotted storage is also removed when users on the account drop under 5. Thus unlimited storage is unfeasible to attain with Google Drive's new restrictions.
; Sugarsync	: Limited to 80,000 files per top level sync folder. To workaround, you can create multiple syncing folders, but each top level folder is limited to 80k files. Also, Microsoft outlook and Apple iTunes databases are unsupported.<ref>{{Cite web|url=https://support.sugarsync.com/hc/en-us/articles/204715554-SugarSync-desktop-app-limitations|title=Sugarsync desktop app limitations}}</ref>
; Trustbox     : A 3-layer encrypted storage supports privacy for an unlimited file version retrieval. Restore any file from any point in time.<ref>{{cite web|url=https://trustbox.dk|title=Trustbox backup}}</ref>
