====================================================================================
#### MySQL Restores
There are 2 types of database restore we can look to perform through commvault, depending on the type of backups in use.
If the client has MySQL level backups, see here
If the client only had file-level backups, see here
====================================================================================
##### MySQL level backups
Starting the restore job
Commgui > Client Servers > Ctrl+F > Search SID > Double Click MySQL > Double Click SID
Right click > All tasks > browse and restore > Untick Recover > Select Required Date using end time
Select Required Database from the list > Recover Selected
#### Post-restore action
Replaying bin logs
```
cp –a DBNAME DBNAME.sql
```
Check disk space before replaying
```
mysqlbinlog -v --database="DBNAME" RESTOREPATH/BINFILENAME.* >> RESTOREPATH/DBNAME.sql
```
Once the bin logs have been replayed, we need to remove USE staments:
```
grep -i ^USE DBNAME
sed -i '/^[uU][sS][eE] /d' DBNAME
```
##### Replaying bin logs to a certain time:
https://kb.ukfast.net/MySQL#Bin\_Logs
Once the bin logs have been been replayed, we can look to remove the bin logs and older db copy
------------------------------------------------------------------------------------------------------------------------------------------
#### Restoring a specific table from DB level backups
------------------------------------------------------------------------------------------------------------------------------------------
Identify the line number of the desired table in the dump file:
grep -in 'dumping data for' dumpfile.sql
Next, we need to remove the lines before and after the desired table
sed -i '10611,28206d' m2meandemcom.sql
The 2 numbers here are the line number of the next table (shown in the original grep command) and the final tables line number (also in the dump)
Next we do the same for the table line numbers before the one we need:
sed -i '51,10581d' m2meandemcom.sql
====================================================================================
#### File level database restore
====================================================================================
#### File Level Restores
====================================================================================
#### eCloud VPC Restores
------------------------------------------------------------------------------------------------------------------------------------------
##### Commvault VM Level Backup Restore:
CommGUI > Client Computers > ctrl+f > VM ID/VPC Instance ID > right click > browse and restore > Full Virtual Machine > Select End time (if required) > Browse > Select VM > Restore full VM > Select Restore DataStore, change name to VMID\_TICKETNUMBER> Go
Vmware > search for restore VM (VMID\_Ticket)
Edit settings (along the top)
**1. Disable Networking**
```
vSphere > VM > Edit Settings > Network Adapter > Disable 'Connect at power on'
```
**2. Power on restore VM**
```
vSphere > VM > Actions > Power > Power On
```
**3. Add swing disk**
Confirm how much space you will require for a swing disk to be used to move data over to the live VM.
```
vsphere > VM > Edit Settings > Add New > Hard Disk > OK
```
Once the disk has been added in vSphere, you'll need to configure this on the server.
Use `mkfs `to initialise the disk filesystem.
```
mkfs /dev/sdX
```
Mount the disk once configured.
```
mount /dev/sdX /mnt
```
**4. Move requested data onto disk**
**5. Unmount the disk from restore VM**
'Once the data has been moved onto the disk, unmount the disk from the server filesystem:
```
umount /mnt
```
And, unmount the disk from the restore VM within vSphere
```
vSphere > Edit Settings > X symbol next to disk we've added. Don't click 'Delete files from datastore'.
```
**5. Transfer the disk to the live VM**
Mount disk on live VM in vSphere
```
Edit Settings > Add New Device > Existing Hard Disk > Datastores > Restores > Identify restore VM > Add restore swing disk
```
Mount the disk on live server filesystem
```
mount /dev/sdX /mnt
```
**6. Move file away from swing disk, into the required location for the client**
**7. Clean up**
Unmount the disk from the live VM
```
umount /dev/diskname
```
Vsphere > edit settings > remove disk > Select 'delete disk from datastore'
Delete the restore VM
vSphere > Restore VM > Actions > Delete from disk > yes
------------------------------------------------------------------------------------------------------------------------------------------
Removing Restore
Once the client has finished with the restore, the disk will need to be unmounted from the server and the restore VM can be deleted.
SSH onto client VPC > df –h > check for /restore > umount /restore
Once the disk has been unmounted:
Vmware > Client VM > Edit Settings > Restore Disk > Remove (X on right side)
Now delete the Restore VM:
Vmware > restore VM > Power Off > Actions > Delete From Disk
------------------------------------------------------------------------------------------------------------------------------------------
Attach disk
Access restored server
Lsblk - find device name
Mkfs /dev/(device name)
Mount /dev/(devicename) /mnt
Main server > edit settings > attach device > existing disk > find disk
On server:
Mount /dev/(devicename) /mnt
Move restored files onto server
