Re: Backup Options for Informix

In Response To: Re: Backup Options for Informix (chrissalch)


the Backup and Restore Guide says in chapter 12 (ontape Config):

Specify a file system directory

You can perform a storage-space (level 0, 1, or 2) archive, or a
logical-log backup to a directory in the file system by using the ontape
utility. For each storage-space archive and logical-log backup, ontape
creates a file in the specified directory. To specify a file system
directory, set the LTAPEDEV and TAPEDEV configuration parameters to the
absolute path name for the directory.

When ontape repeats an archive operation, it renames the existing files
so that old files are not rewritten. A timestamp is added to the file
name, which provides a way for related storage space or logical log
files to be organized together.

To learn about the file naming schema, see ?Rename existing files? on
page 13-6.

and in the forementioned chapter 13 (Backup with ontape):

Back up to a directory

If you choose to back up to a directory, you do not need to provide
tapes. Instead, you back up the data to a directory of a local file
system or a directory that has been mounted on the local system.

The person who runs the backup must have write permission to the
directory. The directory must have enough disk space to hold the
backed-up data. You can use operating system utilities to compress the
data after it is backed up.

Backing up to a directory has the following advantages:

v Multiple instances can simultaneously back up to the same directory
file system.
v You can use operating system utilities to compress or otherwise
process the data.
v You can easily configure your system to automatically back up a log
file when the file is full.

Set the file directory path:

Use the TAPEDEV configuration parameter to specify the absolute path
name on a directory of a file system to use for the storage-space
archive file. This is the destination where ontape writes storage space
data during an archive and the source from which ontape reads data
during a restore. You specify the directory where the logical log backup
files are written with the LTAPEDEV configuration parameter.

Tip: When you back up to a directory file system, specify the -d option
to turn off ontape interactive prompts.

Rename existing files:

When ontape repeats an archive operation, it renames the existing files
so that old files are not rewritten. A timestamp is added to the file
name, which provides a way for related storage space or logical log
files to be organized together.

Renaming conventions:

v Storage-space archive files
The archive checkpoint time is added, and has the format
v Logical log backup files
The backup time is added, and has the format filename_YYYYMMDD_hhmmss.

For example, the file My_instance_L0 is renamed to

When restoring from a file system directory, ontape requires that
storage-space archive and logical-log backup files be named as specified
by the TAPEDEV and LTAPEDEV parameters. If files have been renamed,
including by ontape because of repeated archives and backups, files must
be manually renamed to their original file names.

Override the default name of the archive files:

You can override the default name of the archive files. When TAPEDEV or
LTAPEDEV is a directory path, the default permanent file name consists
of hostname_servernum_Ln (for levels), and
hostname_servernum_Lognnnnnnnnnn (for log files). You can override the
prefix part of the permanent file name, hostname_servernum, by setting
the environment variable IFX_ONTAPE_FILE_PREFIX.

For example, if you set IFX_ONTAPE_FILE_PREFIX to ?My_Instance?, then
during archive, the files are named My_Instance_L0, My_Instance_L1,
My_Instance_L2, and, My_Instance_Log0000000001,
My_Instance_Log0000000002, and so on. During restore, ontape searches
for files in the TAPEDEV directory with file names like My_Instance_L0,
and searches for files in the LTAPEDEV directory with file names like

Not sure where you were "reading around" all day ... :)
