Percona XtraBackup has implemented new tool, The xbcloud Binary, which can be used to upload/download full or part of xbstream archive from/to cloud. This talk will explain and demonstrate this new feature available in Percona XtraBackup 2.3, which is currently in beta.

7. Configuring Percona XtraBackup
[xtrabackup]
compress
compress-threads=4
encrypt=AES256
encrypt-key='VERY_VERY_VERY_VERY_INSECURE_KEY'
encrypt-threads=4
stream=xbstream
[xtrabackup_decompress_decrypt]
decompress
decompress-threads=4
decrypt=AES256

8. Configuring Percona XtraBackup
[xtrabackup]
compress
compress-threads=4
encrypt=AES256
encrypt-key='VERY_VERY_VERY_VERY_INSECURE_KEY'
encrypt-threads=4
stream=xbstream
[xtrabackup_decompress_decrypt]
decompress
decompress-threads=4

[xbcloud]

9. Taking Full Backup
Backup:
export date=`date '+%Y-%M-%d_%H-%M-%S'`
xtrabackup --backup | xbcloud put "Full/$date"
Show Backup:
swift list Backup
9

10. Recovering Full Backup
Get Data:
mkdir /restore
xbcloud get Full/2015-05-22_23-05-55 | xbstream -x -v -C /restore
Decompress & Decrypt:
xtrabackup --defaults-group-suffix=_decompress_decrypt --target-dir=/restore
Prepare the backup (in this example, with incremental support):
xtrabackup --prepare --apply-log-only --target-dir=/restore
Copy Back:
xtrabackup --copy-back --target-dir=/restore
chown -R mysql:mysql /var/lib/mysql
10

11. Taking Incremental Backup
More Challenging to get LSN, with encrypted backups
export incrdate=`date '+%Y-%M-%d_%H-%M-%S'`
xtrabackup --backup
--incremental-lsn=`xtrabackup_swift_encrypted_incremental_lsn
Backup Full/2015-05-22_23-05-55` |
xbcloud put "Incremental/$incrdate"
11

12. Getting LSN For Incremental
Encrypted Backups
xtrabackup_swift_encrypted_incremental_lsn:
#!/bin/bash
container=$1
backuppath=$2
encryptionkey=/root/swift.key
tmpdir=`mktemp -d`
( swift download -o - $container
$backuppath/xtrabackup_checkpoints.xbcrypt.00000000000000000000;
swift download -o - $container
$backuppath/xtrabackup_checkpoints.xbcrypt.00000000000000000001) |
xbstream -x -C $tmpdir
cat $tmpdir/xtrabackup_checkpoints.xbcrypt |
xbcrypt -d -a AES256 -f $encryptionkey |
grep to_lsn | awk '{print $3}'
rm -rf $tmpdir
12

13. Recover Incremental Backup
Lets get the incremental from Swift:
Decompress & Decrypt:
xtrabackup --defaults-group-suffix=_decompress_decrypt
--target-dir=/restore_incremental
Apply the incremental on the already prepared full
xtrabackup --prepare --apply-log-only
--target-dir=/restore/ --incremental-dir=/restore_incremental
Restore:
xtrabackup --copy-back --target-dir=/restore
mkdir /restore_incremental
xbcloud get Incremental/2015-36-22_23-36-54 | xbstream -x -v -C /restore_incrementa
