iphone - How can I migrate my user-generated data to the computer? -

-

i have query regarding backup of third party application data on pc.

i developing application can store photos, text, recordings. user can add number of photos or recordings.

so @ runtime, size of application storage go on increasing. user never want loose data storage limited. hence taking backup of data on computer , deleting iphone seems essential.

so standard way of taking backup of third party application data?

is there way can save data on mac windows using itunes?

is there limit on amount of storage third party application can take?

itunes perform complete backup of iphone when plugged in sync, contain application-specific data files. however, way restore restore entire system image, emergency backup, not need.

third parties have typically provided own backup , synchronisation strategies. there 2 broad approaches:

  • in conjunction companion desktop version of same application (eg. omnifocus, things, 4 track)
  • using web service (eg. darkslide flickr)

the web services typically accessed via ajax api (or equivalent), take longer backups of large files. desktop sync products provide own (eg. omnifocus uses webdav server) , use internal sync engine keep things date, , can sync using wifi connection.

so either way, going have write own server handle own backups, , deal appropriately file types , metadata. don't know of third-party solution this, if 1 exists, generic, , may not suit particular needs (eg. file formats, etc).

so standard way of taking backup of third party application data?

write own sync server , connect via wifi. start looking @ webdav, can build on top easily.

is there way can save data on mac windows using itunes?

itunes full system backup. best bet write sync server portable.

is there limit on amount of storage third party application can take?

afaik there no per-application storage limit on iphone. if provide own solution, archive older 30 days onto mac/pc, keeping recent files. allow them choose "favourites" , kept on iphone regardless of age.
