ttBackup使用说明
c:\>ttBackup -h
Usage:
ttBackup [-h | -help | -?]
ttBackup [-V | -version]
ttBackup -dir <directory> [-type <backupType>] [-fname <fileprefix>]
[-force] {<DSN> | [-connstr] <connStr>}
options:
-h | -help | -? Prints this message and exits.
-V | -version Prints the release number and exits.
-type <backupType> The type of backup to be performed. Supported backup
types are given below. Default is "fileFull".
-dir <directory> The directory in which to store the backup files.
-fname <fileprefix> The file prefix for the backup files in the backup
directory. Default is the base filename portion of the
DataStore parameter of the data store to be backed up.
-force Destroy existing backup files before performing backup
(full file-based backups only).
<DSN>, <connStr> The DSN or ODBC connection string of the data store to
be backed up.
Backup types are:
fileFull Full backup to the specified backup directory. The
resulting backup is not enabled for incremental backup.
This is the default backup type.
fileFullEnable Full backup to the specified backup directory. The
resulting backup is enabled for incremental backup.
fileIncremental Incremental backup. Augments pre-existing backup given
by '-dir' and optionally '-fname'.
fileIncrOrFull If incremental backup is possible, then behaves like
"fileIncremental"; else behaves like "fileFullEnable".
NOTE: For above types, '-dir' is required; '-fname' and '-force' are optional.
streamFull Full backup to the standard output. '-dir', '-fname' and
'-force' are ignored.
incrementalStop Does not perform a backup. Disables an incremental-enabled
backup. '-dir' is required; '-fname' is optional; '-force'
is ignored.
ttBackupStatus函数说明
全备和增量备份
--全备并启动增量备份功能
c:\>ttbackup -dir E:\oracle\timesten\tt_back\full -type fileFullEnable -fname xifenfei01_ -force my_ttdb
Backup started ...
Backup complete
Command> call ttBackupStatus ();

--增量备份
c:\>ttbackup -dir E:\oracle\timesten\tt_back\full -type fileIncremental -fname xifenfei01_ -force my_ttdb

--补充说明
1.需要使用fileFullEnable启动增量备份
2.增量备份需要指定dir和fname和全备时一致
fileIncrOrFull测试
c:\>ttbackup -dir E:\oracle\timesten\tt_back\full -type fileIncrOrFull -force -fname xifenfei01_ my_ttdb
Backup started ...
Backup complete
Command> call ttBackupStatus ();
< 2, 0, 0, 2012-02-22 23:47:57.997000, 2012-02-22 23:47:58.174000, 0, 11880448,0, 5740 >

c:\>ttbackup -dir E:\oracle\timesten\tt_back\full -type fileIncrOrFull -force -fname xifenfei00_ my_ttdb

--补充说明
在有启用增量备份(启用增量的全备或者增量备份本身)的基础上，会自动进行增量备份;
在无启用增量备份(没有备份或者备份没有启用增量备份)的基础上，如果无则会进行全备
streamFull测试
c:\>ttBackup -type streamFull my_ttdb>E:\oracle\timesten\tt_back\full\xifenfei.tream
Backup started ...

--补充说明
在linux/unix环境中，执行流备份可以结合dd命令
如:ttBackup -type streamFull FastIns | dd bs=64k of=/dev/rmt0
