TODO (some of these items mine, some from original Updraft awaiting review): |
| 15 |
//Add DropBox and Microsoft Skydrive support |
| 16 |
//Backup record should include *where* the backup was placed, so that we don't attempt to delete old ones from the wrong place? (Or would that be unexpected to users to have things from elsewhere deleted?) |
| 17 |
//improve error reporting. s3 and dir backup have decent reporting now, but not sure i know what to do from here |
| 18 |
//list backups that aren't tracked (helps with double backup problem) |
| 19 |
//investigate $php_errormsg further |
| 20 |
//pretty up return messages in admin area |
| 21 |
//check s3/ftp download |
| 22 |
|
| 23 |
//Rip out the "last backup" bit, and/or put in a display of the last log |
| 24 |
|
| 25 |
Encrypt filesystem, if memory allows (and have option for abort if not); split up into multiple zips when needed |
| 26 |
// Does not delete old custom directories upon a restore? |
