Manticore Search index dump utility

Used for logical backup of indexes and exceptions, stopwords and wordforms files.
For a physical backup of the index files, use indexbackup

To work correctly, all text fields must be stored. If the field is only indexed - you can not get the original data.
If the index specifies absolute path for the exceptions, stopwords and wordforms files, they are required for backup.
File paths are automatically changed to current_directory/index_name/file_name. To back up these files, you need to have read access or use sudo

WARNING: Testing only on Manticore Search 5 for RT indexes

Quick start

$3

``shell
:/var/backup# yarn global add indexdump
`

$3

`shell
:/var/backup# indexdump --dry-run test_index
`

$3

`shell
:/var/backup# indexdump test_index > test_index.tar.gz
`

$3

`shell
:/var/backup# tar -xOzf test_index.tar.gz dump.sql | mysql -P9306
`

$3

`shell
:/var/backup# indexdump --help
`

$3

`shell
:/var/backup# indexdump -v
`

Full sample dump to AWS s3

$3

For this example, you must have aws-cli configured

Dumping indexes is associated with transferring large amounts of data, so you need to set the chunk size for aws s3

I use eu-central-1 but you can choose any available

`shell


~/.aws/config


[default]
region = eu-central-1
output = json
s3 =
multipart_chunksize = 256MB
`

$3

`shell
:/var/backup# aws s3 mb s3://bucketname --region=eu-central-1
`

Check result

`shell
:/var/backup# aws s3 ls
`

$3

`shell
:/var/backup# indexdump --dry-run limit=10 --all
`

$3

`shell
:/var/backup# indexdump --add-drop-index --all | aws s3 cp - s3://bucketname/alldump.tar.gz
`

$3

#### Extract exceptions, stopwords and wordforms files

`shell
aws s3 cp s3://bucketname/alldump.tar.gz - | tar -C . -xzf --exclude="dump.sql" -
`

#### Restore indexes dump

`shell
aws s3 cp s3://bucketname/alldump.tar.gz - | tar -xOzf - dump.sql | mysql -P9306
