### Added
|
||||
- Drive items backup and restore link shares
|
||||
- Restore commands now accept an optional top-level restore destination with the `--destination` flag. Setting the destination to '/' will restore items back into their original location.
|
||||
- Restore commands can specify item collision behavior. Options are Skip (default), Replace, and Copy.
|
||||
|
||||
### Fixed
|
||||
- Return a ServiceNotEnabled error when a tenant has no active SharePoint license.

## Advanced Restores
|

|

You can control where your data gets restored, and what happens if restored items would overwrite existing
|
||||
ones. Let's restore a folder in OneDrive back to its original location. Since the folder already exists, we can
|
||||
tell corso to with duplicate names as copies.

# Restore Options
|
||||
|
||||
import CodeBlock from '@theme/CodeBlock';
|
||||
import Tabs from '@theme/Tabs';
|
||||
import TabItem from '@theme/TabItem';
|
||||
import {Version} from '@site/src/corsoEnv';
|
||||
|
||||
The default restore command is an great way to restore data in a non-destructive
|
||||
manner to a new folder. When you need more control over the results you can
|
||||
use the advanced configuration options to change where and how your data
|
||||
gets restored.
|
||||
|
||||
## Destination
|
||||
|
||||
The `--destination` flag lets you select the top-level folder where Corso will
|
||||
write all of the restored data.
|
||||
|
||||
### The default destination
|
||||
|
||||
<CodeBlock language="bash">{
|
||||
`corso restore onedrive --backup abcd`
|
||||
}</CodeBlock>
|
||||
|
||||
If the flag isn't provided, Corso will create a new folder with a standard name:
|
||||
`Corso_Restore_<current-date-time>`. The default restore folder is always newly
|
||||
created, and can't interfere with any existing items. If you're concerned about
|
||||
data integrity then this is always the safest option.
|
||||
|
||||
### An alternate destination
|
||||
|
||||
<CodeBlock language="bash">{
|
||||
`corso restore onedrive --backup abcd --destination /my-latest-restore`
|
||||
}</CodeBlock>
|
||||
|
||||
When a destination is manually specified, all restored will appear in that top-level
|
||||
folder. In the example above, Corso will restore everything into `my-latest-restore`.
|
||||
If that folder doesn't already exist, Corso will automatically create it. If it does
|
||||
exist, the restore will use the existing folder, allowing you to restore to the same
|
||||
folder multiple times.
|
||||
|
||||
### The original location
|
||||
|
||||
<CodeBlock language="bash">{
|
||||
`corso restore onedrive --backup abcd --destination /`
|
||||
}</CodeBlock>
|
||||
|
||||
You can restore items back to their original location by setting the destination
|
||||
to `/`. This skips the creation of a top-level folder, and all restored items will
|
||||
appear back in their location at the time of backup.
|
||||
|
||||
### Limitations
|
||||
|
||||
* Destination won't create N-depth folder structures. `--destination a/b/c`
|
||||
doesn't create three folders; it creates a single, top-level folder named `a/b/c`.
|
||||
|
||||
* Exchange Calendars don't support folder hierarchy. If your backup contains the
|
||||
calendars `MyCalendar` and `Birthdays`, and you restore to `--destination Restored`,
|
||||
all of the restored calendar events will appear in the `Restored` calendar. However,
|
||||
if you restore events in-place (`--destination /`) then all events will return to
|
||||
their original calendars.
|
||||
|
||||
* When restoring Exchange Calendar Events to a destination folder, Events that were
|
||||
safe in different calendars may collide with each other in the destination calendar.
|
||||
|
||||
## Item collision handling
|
||||
|
||||
When restoring data into an existing folder, the items restored may conflict
|
||||
with existing data. When this happens, Corso resolves the conflict using its
|
||||
collision configuration.
|
||||
|
||||
Collision detection differs between each service and type of data. The general
|
||||
comparison always follows the same pattern: "within the current folder, if the
|
||||
restore item looks identical to an existing item, it collides."
|
||||
|
||||
The comparison uses item metadata (names, subjects, titles, etc), not item content.
|
||||
If the current `reports.txt` has different contents than the backup `reports.txt`,
|
||||
it still collides.
|
||||
|
||||
Collisions can be handled with three different configurations: `Skip`, `Copy`,
|
||||
and `Replace`.
|
||||
|
||||
## Skip (default)
|
||||
|
||||
<CodeBlock language="bash">{
|
||||
`corso restore onedrive --backup abcd --collisions skip --destination /`
|
||||
}</CodeBlock>
|
||||
|
||||
When a collision is identified, the item is skipped and
|
||||
no restore is attempted.
|
||||
|
||||
## Copy
|
||||
|
||||
<CodeBlock language="bash">{
|
||||
`corso restore onedrive --backup abcd --collisions copy --destination /my-latest-restore`
|
||||
}</CodeBlock>
|
||||
|
||||
Item collisions create a copy of the item in the backup. The copy holds the backup
|
||||
version of the item, leaving the current version unchanged. If necessary, changes
|
||||
item properties (such as filenames) to avoid additional collisions. Eg:
|
||||
the copy of`reports.txt` is named `reports 1.txt`.
|
||||
|
||||
## Replace
|
||||
|
||||
<CodeBlock language="bash">{
|
||||
`corso restore onedrive --backup abcd --collisions replace --destination /`
|
||||
}</CodeBlock>
|
||||
|
||||
Collisions will entirely replace the current version of the item with the backup
|
||||
version. If multiple existing items collide with the backup item, only one of the
|
||||
existing items is replaced.
