Path lenght on Office 365 OneDrive

Postby gandalf on Mon Aug 22, 2016 12:14 pm

Hi,
I'm trying to use Syncovery with Office 365 OneDrive cloud service.
The per user 1TB Office 365 cloud space is very interesting for backup purposes.
No problems to define a profile and register Syncovery into Office 365 administration portal.
While Microsoft broked the maximum file number limit (was 20000), what remains as a critical limitation is path lenght for the file tree we are backing up.
This limit (256 bytes) is not compatible with modern company folder/file structures and it is not immaginable to suggest renaming hundred thousand existing long file/folder names.
I only see two ways to overcome this limit (with OneDrive F.B. as destination):
1 - Zipping the structure using a short-name coding for zip files
2 - Renaming files and folders with short name, manteining a table for names transcoding.
Fist solution is ready inside Syncovery, but you loose updating file by file every running of backup instance.
Every time you execute backup profile you simply add a new big zip structure.
I could not find in Syncovery a way to implement the second solution.
Some suggestion ?
Thanks in advance,
G.

Hello,
in this case I can only suggest using a different cloud storage provider. Syncovery cannot shorten paths.

You could try Amazon S3, Microsoft Azure, Google Drive, DropBox, Google Nearline, Backblaze B2 and others.

I think that Office 365 customers are not going to choose any other cloud storage services.
They already have Office 365 for Exchange online services and Office ProPlus packages.
This also means having 1 TB free cloud space for each O365 account payed: they will not change, they will not pay more for a different cloud service.
They will choose a backup / sync software if able to backup on their cloud service, not the opposit.
So, I have to find a solution to backup their structures to the path-lenght-limited OneDrive/SharePoint space.

Syncovery cannot shorten paths
.
True, but there is a midway solution, used by other backup / sync software: when I choose to compress target files (or groups of files, or folders) I can retain original name for files & folders for ZIP files (this doesn't solve path lemght limit) or use an in some way coded zip name for files and folders.
In other words, you don't change original file & folder names inside the zip's, but zip names are coded and short.
I'm looking at the compression option in Syncovery Zip/Encryption where "Use ZIP Packages" permits
"Use Profile Name for ZIP File name", but it is not clear what Syncovery will do updating the structure.
I didn't find documentation on it.
Best regards

The Zip Packages feature is very limited in functionality, so probably not suitable for this purpose. Syncovery cannot update existing Zip Packages, it cannot even see them or know what's inside them.
