All data backup / restore to point in time
Although I appreciate backups are constantly being taken by Zoho it would be good to be able to backup / restore the entire organisation at a specific point in time. This would be particularly useful when testing as it would be possible to have a "clean" copy of the account which can be restored when testing is complete.
Ongoing it would again be useful when entering large amounts of updates via the API to be able to "wind back" the data to a point when you know the data is "clean".
For an "accounting" application, backups every 15 days is poor. Zoho should have programmed an automated daily backup to external sites: google, amazon, sftp, dropbox, etc. The developers should not all take off the same day: Good Friday.
