Hi,
Server backup on below schedule.
A file "A.txt" has modified on below day
And it was deleted in accident
===================================================
My question are:
1) Differential backup on Monday, Tuesday, Friday will not start since files hasn't modified ?
2) After accident delete, for latest backup I can use is "backup on Thursday" ?
3) Or I need to restore "Full backup" then "backup on Thursday" ?
4) Differential backup will backup Entitled file or just modified bit only ?
Thanks !

...read the Admin Guide...you'd use the last DIFF and then FULL.

As suggested above, pls have a look @ the Admin Guide. Verbatim from the Admin Guide -
Differential backups include all files that have changed since the last full backup or incremental backup. The difference between differential and incremental backups is that differential backups are cumulative. After a differential backup, each subsequent differential backup backs up the same files as the previous differential
backup. It also backs up as any new files or changed files dating back to the last full backup or incremental backup.
Restoring requires the latest full backup and the latest differential backup.

Hi,
I have read but not really understood. Is every differential backup compare with full backup ?

Test your restores as this is the only way you will know. You should be able to take a DIFF backup from any day and then restore from that along with the FULL. If your FULL is corrupted I'd assume you can't restore anything.

Yes.

Hi,
But for restore,
1) Put both "Full" and "Differential" into library
2) Restore file / folder from "Full" backup to "C:\restore"
3) Restore file / folder from "Differential" backup to "C:\restore"
Am I right ?
If I want to restore file on 8 Aug 2015, then I should select differential backup on 8 Aug to restore first or full backup to restore first ?
Thanks

Full backup is restored first followed by the differential.

...have you actually tried to test this?
