- | Since the AhsayOBM / AhsayACB backup client cannot detect the backup source location or files/folders, they will be treated as deleted by the AhsayOBM / AhsayACB backup client the data on the backup destination(s) will be moved to the retention area. **Where they will be permanently removed after they exceed the retention policy setting for the backup set.** | ||
- | <br> | ||
- | <br> | ||
- | This document contains instruction on how to rollback such action (e.g. manually un-delete the data), so the data does not need to be re-uploaded again after the backup source drive is reconnected or permission settings of files/folders were corrected. | ||

- | ===== Steps ===== | ||
- | <html> | ||
- | The following assumptions are made: | ||
- | <br> | ||
- | <ul> | ||
- | <li><font color=black>Previous backup was performed on March 20, 2018 01:00:00.</font></li> | ||
- | <li><font color=black>The backup source drive was disconnected before the sub-sequence backup, performed on March 21, 2018 03:00:00.</font></li> | ||
- | <li><font color=black>Data backup by the previous job to backup destination AhsayCBS were detect and retain as deleted data.</font></li> | ||
- | <li><font color=black>You want to revert the data snapshot the previous backup on March 20, 2018 01:00:00.</font></li> | ||
- | </ul> | ||
- | |||
- | <font color=red>Important:</font><font color=black> | ||
- | <br> | ||
- | It is recommended to temporarily suspend the backup user to ensure that no backup / restore job is performed during the manual un-delete process.</font> | ||
- | <br> | ||
- | <br> | ||
- | Refer to the following steps to un-delete the data: | ||
- | <br> | ||
- | <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> | ||
- | <li><font color=black>Select <b>Backup User</b>, and the corresponding backup user, then <b>Backup Set</b>. </font></li> | ||
- | <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:58%; border:thin solid black" src="http://wiki.ahsay.com/lib/exe/fetch.php?media=public:obtain_backupset_id.png"/> | ||
- | </ul> | ||
- | </li> | ||
- | <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 on Windows | ||
- | <br> | ||
- | <br> | ||
- | E:\user\Username\1517279516004\blocks | ||
- | <br> | ||
- | <br> | ||
- | <img style="width:68%" src="http://wiki.ahsay.com/lib/exe/fetch.php?media=public:undelete_1.png"/> | ||
- | <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.  All files backed up by that job are stored in that particular folder. | ||
- | </li> | ||
- | <br> | ||
- | |||
- | <li><font color=black>Remove (or move to another location) 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.metadata.cgz</font></font></li> | ||
- | </ul> | ||
- | <br> | ||
- | <img style="width:68%" src="http://wiki.ahsay.com/lib/exe/fetch.php?media=public:undelete_2.png"/> | ||
- | </li> | ||
- | <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 March 20, 2018 01:00:00, browse to | ||
- | <br> | ||
- | <br> | ||
- | E:\user\Username\1517279516004\blocks\<font color=red>2018-03-20-01-00-00</font> | ||
- | <br> | ||
- | <br> | ||
- | Copy | ||
- | <br> | ||
- | <br> | ||
- | E:\user\Username\1517279516004\blocks\<font color=red>2018-03-20-01-00-00</font>\index.db.*.cgz<br> | ||
- | E:\user\Username\1517279516004\blocks\<font color=red>2018-03-20-01-00-00</font>\index.metadata.cgz<br> | ||
- | <br> | ||
- | <br> | ||

- | <br> | ||
- | <br> | ||
- | <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> | ||
- | |||
- | |||
- | <li><font color=black>Ensure that the issue to the backup source drive is resolved, then perform another backup job afterward. | ||
