Looking for tape drive backup replacements?

2010-12-02T08:24:00.000-08:00

Most people today are getting tired of having to replace tape drives every couple of years. Tape drives are getting more expensive and become less durable over time. Here is what the market has found to be a cheaper more reliable solution. The Tanberg RDX and the Dell RD1000. Both act like tape drives, but use a hard disk drive as its backup media. Lets compare!

Comparisons	Tape Drives	RD1000 & RDX Backup Drives
Average Cost for a unit	$500 - $2000	$100 - $350
Average Cost for media (2)	$100 - $300	$200 - $400
Average Life of unit	2-4 years
Reliable Multiple backups on 1 media	NO	YES

New postNDR program

2010-09-21T07:59:00.001-07:00

DESTRUCTIVE RESTORE after a full NON DESTRUCTIVE RESTORE

--------------------------------------------------------

postNDR ${Ver}

1. NDR stands for Non-Destructive-Restore.

2. In the event you install a fresh OS on a new hard drive, and want

to restore the data from a previous systems LONE-TAR Backup,

a Non-Destructive-Restore will PREVENT any of the files that exist

on the NEW hard drive from being clobbered by files that exist on

the LONE-TAR backup media.

3. However, there are certain files that you DO want to over-write

from the LONE-TAR backup media to the new hard drive (assuming same OS).

4. Prior to any crash and while your system is up and running,

postNDR will create a tarball with these desired files and directories.

5. After a Non-Destructive-Restore, simply restore this tarball and all

printers, startup scripts, and root profiles will be put back in place.

6. It is recommended that you execute this script from within your roots

crontab file 20 minutes PRIOR to your LONE-TAR nightly backup. EXAMPLE:

10 2 * * 1,2,3,4,5 /usr/lone-tar/postNDR -backup

30 2 * * 1,2,3,4,5 exec /usr/lone-tar/ltar.M.cron 1

" ; rtn2 ; clear ;

echo " --------------------------------------------------------

DESTRUCTIVE RESTORE after a full NON DESTRUCTIVE RESTORE

--------------------------------------------------------

postNDR ${Ver}

7. The file name that contains the inclusion list of files to archive is:

${NDR_lst}

8. The '-create' flag will create a generic inclusion list. If this

inclusion file list does not exist, it will be automatically created.

9. The list of files and directories in this file MUST be viewed and

and confirmed by your systems administrator. Add or delete files or

directories to this list to serve your needs using the '-edit' flag.

**CAUTION** Symbolic links MUST have the real file in the list as well.

10. Do NOT use wild-cards in your inclusion list.

11. If a file name exists in your inclusion list, and does not exist on

the system, it will simply be ignored.

12. Please report to 'support@cactus.com' any files that should be ADDED

to this generic script that may have been over looked.

LONE-TAR Command-line Syntax v4.3.x

2010-09-04T20:15:00.001-07:00

Command Example 1: Backup a single file/directory

Backup Device >>> /dev/st0
Block Factor >>> 20
Directory being backed up >>> /bin

# cd /
# lone-tar Cvfb /dev/st0 20 ./bin

This command-line calls the LONE-TAR program and indicates:

C create an archive using no compression
v display files being backed up on the screen but keep NO catalog
f use the device which is named /dev/st0
b block size of 20 for the media

As you can see, the C and v has no argument, while the f, b functions do. Notice there is no flag for the directory you want backed up. Just place whatever files or directories you wish to backup after all the proper flags and arguments.

Command Example 2: Backup multiple files/directories

Backup Device >>> /dev/rStp0
Block Factor >>> 20
Directories being backed up >>> /bin & /var/spool & /usr2

# cd /
# lone-tar Cvfb /dev/rStp0 20 ./bin ./var/spool ./usr2

C create an archive using no compression
v display files being backed up on the screen but keep NO catalog
f use the device which is named /dev/rStp0
b block size of 20 for the media

The only difference with this example and example 1 is the amount of directories being backed up.

Command Example 3: Backup an inclusion list

Backup Device >>> /dev/rcd0
Block Factor >>> 120
Inclusion List >>> /tmp/Backup.list

# cd /
# lone-tar CvfbF /dev/rcd0 120 ./tmp/Backup.list

C create an archive using no compression
v display files being backed up on the screen but keep NO catalog
f use the device which is named /dev/rcd0
b block size of 120 for the media

F backup all files contained in an inclusion list

Example Contents of the inclusion list /tmp/Backup.list

./usr/backups
./u2/database/user/dan
./usr
./tmp/roster.file

Anytime you make an inclusion list, it is great practice to begin every entry with a’./’

Command Example 4: Backup a single file/directory with compression

Backup Device >>> /dev/st0
Block Factor >>> 120
Directory being backed up >>> /bin

# cd /
# lone-tar Pvfb /dev/st0 120 ./bin

P create an archive using software compression
v display files being backed up on the screen but keep NO catalog
f use the device which is named /dev/st0
b block size of 20 for the media

Command Example 5: Backup an entire system with exclusions

Backup Device >>> /dev/st0
Block Factor >>> 120
Directory being backed up >>> /

# cd /
# lone-tar MvfbE /dev/st0 120 ./usr2

M create a Master Backup Archive
v display files being backed up on the screen but keep NO catalog
f use the device which is named /dev/st0
b block size of 20 for the media
E exclude a file or directory from a backup

So command 5 does a full system backup, but excludes the directory '/usr2'.
You may use as many 'E' flags as much as you want in one command to match the needed exclusions. Or use the 'X' flag to exclude an inclusion list of files and directories.

Command Example 6: Listing of files on an archive

# lone-tar tvfb /dev/st0 20

t lists files on a LONE-TAR archive.
v display files being listed on the screen but keep NO catalog
f use the device which is named /dev/st0
b block size of 20 for the media

Watch and see the tape fly with a list of its contents. The t is mnemonic for table-of-contents.

Command Example 7: Level 1 Verification on an archive

# lone-tar Tvfb /dev/st0 20

T verify files on a LONE-TAR archive using a Level 1 Verification Process.
v display files being verified on the screen but keep NO catalog
f use the device which is named /dev/st0
b block size of 20 for the media

Command Example 8: Level 2 Verification (Byte-by-Byte) on an archive

# lone-tar TTvfb /dev/st0 20

TT verify files on a LONE-TAR archive using a Level 2 Verification Process.
v display files being verified on the screen but keep NO catalog
f use the device which is named /dev/st0
b block size of 20 for the media

This is the verification LONE-TAR uses on EVERY backup from the Menu or from one of our scripts. This is the most recommended way to verify files and is the most used.

Command Example 9: Restore a directory to its original place on the hard drive

# cd /
# lone-tar xvfb /dev/st0 20 ./usr/brad/

x restore files from LONE-TAR archive
v display files being restored up on the screen but keep NO catalog
f use the device which is named /dev/st0
b block size of 20 for the media

This command will restore all the contents of '/usr/brad' to its original place on the hard drive.

**NOTE**
Any time you are doing a restore of a directory and all its sub-contents, please use a trailing '/' at the end of the entry. Otherwise you will just restore the directory name and nothing else.

How to utilize a good backup scheme for Remote or Off-Site Backups

2010-09-03T07:03:00.000-07:00

The biggest issue companies face when doing remote or off-site backups, is the amount of time it takes to complete these backups. Normally companies would do Master backups (Complete System Backups) every day to a tape drive or something local. What if you want to backup to a Remote Site using only a standard cable connection?

The best way around this dilemma is to switch up how you run backups. For example, we at Lone Star ALWAYS recommend this backup scheme when doing it Off-Site:

- Do 2 Master Backups a week (Preferably at the beginning and at the end of the week).
- Do the rest of the days using an Incremental Backup which backs up ONLY the files that have changed since your last successful Master backup.

So if you ever had to deal with a Disaster Recovery Restore using our product, all you would have to do to be back up and running would be to restore your latest LONE-TAR Master backup first, then restore your latest LONE-TAR Incremental backup next. It is that easy.

This method says you time and money! Especially if you are paying an off-site data center money for each GB used.
