Performing System Operation Tasks: 900 Series HP 3000 Computer Systems > Chapter 6 Copying Files to Tape
Storing Files |
|
The next sections teach you how to store:
In addition, you will learn how to respond to tape requests, monitor the progress of the STORE command and display information about the files you are storing.
After you enter a STORE command, STORE issues a message similar to the following on the console:
Monitor the console for additional messages. STORE sends you messages when you need to reply to a tape request, to add a write ring to a tape reel, or to mount a new tape on a backup device. When your backup devices are not configured to be automatically allocated, the system answers your STORE command with one or more tape requests. See chapter 1, "Managing Tapes and Tape Drives" for more information on tape requests. If you have previously issued a FILE command that included the backup device's LDEV number, the tape request asks you to confirm that number. For example,
Use the PROGRESS parameter in your STORE command to display progress messages at regular intervals. To request progress messages every 5 minutes, enter:
The system displays progress messages every 5 minutes.
You see similar messages at regular intervals, for example:
If you use the PROGRESS parameter alone, without specifying an interval, STORE displays progress messages every minute. When STORE has filled a tape but there is additional information to store, it asks you to mount another tape. You see a mount request and an LDEV NOT READY message like the ones below:
To mount another tape:
When you see the END OF PROGRAM message, the STORE process is complete. To be absolutely sure that important files have been stored correctly, it is a good idea to check the file listings and verify that stored files were copied correctly. To store two or more files at the same time, list all the files but separate their names with commas. For example:
Or you can use HFS syntax to specify the files. For example:
To store all files in a single group or account, use a wildcard specification. For example, to store all files and directories in the current working directory, enter:
Or, for example, to store all files and directories in the current working directory and in directories below it that conform to MPE syntax, enter:
Consult Table 6-1 for a list of wildcard characters and character sets. For additional examples for specifyig file sets, see Table 6-2. Occasionally, you may need to rename files as they are stored to tape. For example, renaming files is necessary when the accounting structure of the source machine (the computer where the files are being copied from) is different from that of the target machine (the computer where the files are being copied to). To do so, you can use the RENAME parameter of the STORE command. To copy and rename a file from a source system to tape, create a file equation and specify the source file set (those files on the source system) and the target file set (those on the target system) as shown below.
You may specify the file sets using either MPE or HFS syntax. For more information on renaming files, refer to Volume II of the MPE/iX Commands Reference Manual Volumes 1 and 2 (32650-90003 and 32650-90364). At times it may be easier to describe the set of files you want to store as a large set minus a certain subset. For example, suppose you want to store all files in all groups of the PERSONEL account except the files in the FORMS group. Describe the set of files to store as shown in the following example:
You can describe as many excluded subsets for a set of files as you need (unless you are creating an MPE V/E store tape, which allows only one excluded subset). For example, to store all files in the PERSONEL account except the files in the FORMS and RECORDS groups, enter:
For more information about MPE V/E store tapes, read "To create MPE V/E compatible STORE tapes" later in this chapter. Another way you can use excluded subsets is to store all files and directories that are outside of MPE syntax (that is, create a tape with only HFS-syntax files and directories on it). To do so, enter:
Store multiple sets of files the same way that you store more than one individual file. Separate the file sets with commas in your STORE command. For example, to store all files in the PERSONEL account except the files in the FORMS group and all files in the PAY group of the ACCTG account, enter:
Use the DATE parameter to store only files that have not been accessed since a certain date. This enables you to do, among other things, a partial system backup. For example, suppose a full system backup was performed on May 30, 1994. The following STORE command would copy all system and user files modified since that date:
You must enter the date in the mm/dd/yy format (as shown above) or as mm/dd/yyyy (for example, 05/30/1994). The files stored include any that were modified on the same date as the date entered, and those modified since the specified date on nonsystem volume sets that are online. Use this form of the DATE parameter when you perform regular backups of a file set. For example, store the entire set (a full backup) once a week and store only those files modified since the full backup on all other days. You can also use the DATE parameter to store only files that have not been accessed since a certain date. For example:
You may enter the year as two digits or four digits (94 or 1994). You may want to use this form of the DATE parameter with the PURGE parameter to remove out-of-date files from your system. Refer to the next section for more information. If your system contains infrequently used or out-of-date files, you can store them onto tape and permanently remove them from the system disks at the same time. This process, called archiving files, increases available space and provides a backup copy of the files in case you need them in the future. To store disk files to tape and then delete the disk files in a single operation, use the PURGE parameter of the STORE command. For example, to copy all files in the OLD group of the account ACCTG to tape and delete the files from disk, enter:
PURGE deletes the files only after it has successfully stored all of them. Thus, if STORE terminates in the middle of the process, it does not purge any files. You can combine the DATE and PURGE parameters to archive unused files periodically. For example, the following STORE command stores to tape all files in the personnel directory that have not been accessed since September 2, 1994, and then deletes the disk files:
To use the PURGE parameter with a privileged file or files, you must have system manager (SM), system supervisor (OP), or privileged mode (PM) capability. PURGE requires you to have write access to the file in order to purge it. You may want to warn users before you archive files and inform them how to request to have archived files restored. If you need to restore purged files to the system, you can find them on the tape to which you stored them and on the tapes from the last full system backup you performed before you purged the files. Use the TRANSPORT parameter of STORE to create STORE tapes that are compatible with MPE V/E. For example, to store all of the files in the PERSONEL account onto an MPE V/E compatible tape, enter:
You cannot use HFS syntax to specify the file set when you use the TRANSPORT parameter. The tape that is produced with the TRANSPORT parameter uses the same format as MPE V/E STORE tape format. Therefore, files that are not compatible with MPE V/E (due to file/record size limitations or new file types), are not stored if TRANSPORT is specified. Also, the TRANSPORT parameter is not valid if DIRECTORY, ONVS, or FCRANGE is specified. By default, MPE V/E stores a maximum of 4000 files at a time. If you are storing more than 4000 files using the TRANSPORT parameter, use the FILES= parameter to specify the maximum number of files to be stored. If you do not use the TRANSPORT parameter, the FILES= parameter is not necessary; if included, it is ignored. For example, to set the maximum number of files stored to 6000 for a TRANSPORT tape, you might enter the following:
You cannot use the character set specifications shown in Table 6-1 with the TRANSPORT parameter. Use the MPE V/E RESTORE command to restore files from MPE/iX TRANSPORT tapes to an MPE V/E system. On restore, the backup system automatically detects a TRANSPORT tape and performs the necessary file format translation. To store the files on a particular volume set, use the ONVS parameter of the STORE command. ONVS lets you store files from as many as 20 volume sets at once. For example, to store all files from the nonsystem volume sets named VOL_SET_A and VOL_SET_B, enter:
To store files from system and nonsystem volumes, include the system volume set name within the ONVS parameter. For example:
