-For backup data that were moved to retention un-intentionally,​ for example, when a removable backup source (e.g. faulty hard drive / USB external drive) was disconnected before a backup, the following warning message will be displayed:

-Since the backup client cannot detect the backup source, all backup data are interpreted as deleted by the backup client, therefore, all backup data are moved to retention. 
-<br> 
-<br> 
-Refer to the following steps to revert the index files (e.g. un-delete the data), so that the backup data will not be re-uploaded again when the backup source drive is reconnected. 
-<br> 
-<br> 
-Note:<​br>​ 
-The same steps can also be performed to revert the set of indexes to a healthy state (e.g. reverting to previous indexes from a successful backup when there'​s an index issue with the current set of indexes).

-<font color=red>​Important:</​font><​font color=black> ​ 
-<br> 
-It is strongly recommended to temporarily suspend the backup user to ensure that no backup / restore is performed during the following steps.</​font>​ 
-<br> 
-<br> 
-Refer to the following steps to un-delete the data / revert to a previous set of indexes: 
- 
-<br> 
-<ol> 
-<​li><​font color=black>​On the AhsayCBS web console, obtain the backup set ID of the affected backup set: 
-<br> 
-<br> 
-<ul> 
-<​li><​font color=black>​Under <​b>​Backup / Restore</​b>,​ select <​b>​Users,​ Groups & Policies</​b>​.</​font></​li><​br>​ 
-<​li><​font color=black>​Select <​b>​Backup User</​b>,​ and the corresponding backup user, then <​b>​Backup Set</​b>​. </​font></​li><​br>​ 
-<​li><​font color=black>​Select the affected backup set under <​b>​Manage Backup Set</​b>,​ the backup set ID is listed under <​b>​General</​b>​.</​font>​ 
-<br> 
-<br> 
-</li> 
-<img style="​width:​50%"​ src="​http://​wiki.ahsay.com/​lib/​exe/​fetch.php?​media=public:​8112_1.png"/>​ 
-</ul> 
-</li> 
-<​br><​br>​ 
- 
-<​li><​font color=black>​From the backup destination (e.g. AhsayCBS), browse to the <​b>​blocks</​b>​ folder where the backup data are stored at: 
-<br> 
-<br> 
-%backup_destination%\%backupset_id%\blocks ​ 
-<br> 
-<br> 
-<​u>​For example</​u>​ 
-<br> 
-For backup destination set to AhsayCBS 
-<br> 
-<br> 
-C:\Program Files\AhsayCBS\user\username\1614747242788\blocks

-<br> 
-<br> 
-Note: 
-<br> 
-A separate folder is created for each backup job according to its start time (YYYY-MM-DD-hh-mm-ss),​ under the <​b>​blocks</​b>​ folder. &​nbsp;​All files backed up by that job are stored in that particular folder. ​ 
-</li> 
-<​br><​br>​ 
- 
-<​li><​font color=black>​Remove all index files in the <​b>​blocks</​b>​ folder: 
-<br> 
-<br> 
-<ul> 
-<​li><​font color=black>​%backup_destination%\%backupset_id%\blocks\<​font color=red>​index.db.*.cgz</​font></​font></​li>​ 
-<​li><​font color=black>​%backup_destination%\%backupset_id%\blocks\<​font color=red>​index.db.*.cgz</​font></​font></​li>​ 
-</ul> 
-<br> 
-<img style="​width:​58%"​ src="​http://​wiki.ahsay.com/​lib/​exe/​fetch.php?​media=public:​8112_3.png"/>​ 
-</li> 
-<​br><​br>​ 
- 
-<​li><​font color=black>​Copy the index files from a previous backup job folder (the backup snapshot (YYYY-MM-DD-hh-mm-ss) which you would like to revert to), back to the <​b>​blocks</​b>​ folder. 
-<br> 
-<br> 
-<​u>​For example</​u>​ 
-<br> 
-To revert the backup snapshot to the backup on April 15, 2021 11:02:23, browse to  
-<br> 
-<br> 
-C:\Program Files\AhsayCBS\user\username\1614747242788\blocks\<​font color=red>​2021-04-15-11-02-23</​font>​

-<font color=red>​Important:</​font>​ 
-<br> 
-Once the backup snapshot is reverted, data backup by the latest backup (or sub-sequence backup after the snapshot which you have reverted to) will not be displayed in the restore menu. 
-</​font>​ 
-</li> 
-<​br><​br>​ 
- 
- 
-<​li><​font color=black>​Ensure that the issue to the backup source drive is resolved, then perform another backup job afterward.
