Re: Tape backup policies

[Michael Leone]

Time. Effort. Costs of tapes (especially if we keep one-to-one - i.e.,
each EOM is a separate tape, regardless of how much more can fit on
one tape). Disk space to restore onto. Other things ...

If a tape goes bad (which we've had happen), then we lose only 1 month
data. If we had multiple EOMs on one tape, losing a tape woulfd be
BAD. :-)

Re: Tape backup policies

[Devin Meade]

David,

This is why we moved to online archives only.  It requires more disk space
and periodic review, but disk space is cheap and so is my time!  We had DDS1
tapes written in Palindrome Network Archivist, some from the late 80's or
so, we had DDS2, DDS3, DDS4, DLTIV, DLT S320 and now DLTS4.  We even had
some archive CD's that could not be read, lucky we had offsite copies of the
CD's which were readable.  I guess I can't store them on my dashboard :-).

RE: Tape backup policies

Why not do a one-time restore of really old backups to your newer backup 
medium? That way you can always use your current SW for a restore from any time 
frame.

Or drives .. I have a stand-alone SDLT320 and stand-alone SDLT600 tape
drive, attached to a server other than my current backup server,
specifically for the reason of reading old tapes.

It becomes more aggravating when I need an old ArcServe tape, instead of
more current Networker. That's why I have a separate machine that is a
Networker storage ndoe, that also has ArcServe installed on it. So I can
start whichever backup program I need, to do restores.

Re: Tape backup policies

[Devin Meade]

We have a data retention policy driven by lawyers.  Our offsite backups are
tape via Disk-to-Disk-to-Tape.  These tapes are explicitly NOT to be used
for long term retention, ie our tapes are rotated in about a year.  Our
policy drives what is kept long term and short term.  Where they are kept
doesn't matter but we have a separate fileshare with "Permanent Archives"
and "Interim Archives".  The perm archives are kept indefinitely (pretty
much construction drawings only).  Our Interems are kept for various
timeframes based on type - with a max of 5 years ... then they get deleted.
FYI We are considering some online backup systems for offsite DR but we need
more work to pay for it.

Re: Tape backup policies

[RichardMcClary]

+1 on the documentation!

Last read-through of PCI standards, there were not that many specifics as 
to how many, how long, how often, etc.  What was explicit, though, was 
that a written policy be in place, that it is adhered to, and that the 
destruction of old media be documented.

In addition to this excellent point, it should be noted that an 
excessively long retention period could be as bad as having too short of a 
retention period, as it opens you up to greater electronic discovery in 
the event of legal action.

Choose wisely, and work with senior management and legal counsel to 
develop the right data management policies.

Barring conflicts with regulatory requirements, I typically try to work 
towards the following:

-- Daily Backups maintained for up to 15 days
-- Weekly Backups maintained for up to 5 weeks
-- Monthly backups for up to 12-24 months
-- Annual backups for up to 2 or 3 years (optional if maintaining 24 
monthly backups)

Some systems might have more stringent retention, for example a key 
database system maintaining 30 daily and 52 weekly backups.

Whatever the configuration, it should be documented.

Re: Tape backup policies

[Joseph Heaton]

Well, the number of tapes depends on how much data, really.  Here, we send 
about 10TB to tape each week.

But, we keep weekly backups for 6 weeks, and monthly backups for 400 days.  
Weeklies go to an office about 6 blocks away, and monthlies go to Iron Mountain.

Or drives .. I have a stand-alone SDLT320 and stand-alone SDLT600 tape
drive, attached to a server other than my current backup server,
specifically for the reason of reading old tapes.

It becomes more aggravating when I need an old ArcServe tape, instead of
more current Networker. That's why I have a separate machine that is a
Networker storage ndoe, that also has ArcServe installed on it. So I can
start whichever backup program I need, to do restores.

RE: Tape backup policies

[Terry Dickson]

Exactly problem we faced, our solution was to read tapes on old drive and write 
again on new drive.  However if you have multiple drives and the right type of 
software you can archive directly from one tape to another.

Here is something I don't recall being discussed...

LTO1 may be read by an LTO3 drive.  Our LTO3 tapes supposedly can be read by 
our new LTO5 drive...

What I'm getting at is, keeping "forever" may require moth-balling machines so 
they can be read if necessary

RE: Tape backup policies

[Orland, Kathleen]

I have 12 weekly tapes (9 daily tapes, 3 full backup tapes). That gives me 2
weeks of daily backups and 3 full backups on weekends, then a month end tape
is used so I have plenty to fall back on in the event of data loss or
corruption (or in our case, server hardware failure which has occurred
once).  

I transport them myself in a Turtle Case. 

I have 72 month end tapes, kept in Turtle Cases. 72 months = 5 years. 

Off site storage is my kitchen.

Hello everyone.

For those who are still backing up to tape.

What do you guys have for tape backup policies?

I'm curious as to how far back you are keeping tapes - 1 year? 5 years?

I've typically seen a 10 tape rotation w/ a monthly tape put in offsite
storage.

Is this still common practice?

"still" :-) I think that tape is still - by far - the majority of backup
targets ...

I know we literally have tapes stored offsite from the mid 90s ...
otherwise, I know we've never erased a month end or other such archived
tape.

We did a 2 month rotation, and every EOM tape stored offsite.

RE: Tape backup policies

[Guyer, Don]

.as well as what's being backed up. It might be a SQL DB that the
business unit wants backed up twice daily for faster recovery purposes.
Most places I've worked at did the 2-week rotation, with a perm monthly
tape like you mentioned.

 

A lot of factors to take into consideration, involving other BUs and
mgmt.

That's really a question for your management.  Your business type and
other laws/guidelines will tell you how long you need to keep your data,
the media it's put on is irrelevant.  When we were still backing up to
tape we did a daily full backup 4 week rotation with a month end and
then kept the year end forever.

RE: Tape backup policies

[Terry Dickson]

OK I am over cautious, and we have a small data store in comparison to many on 
the list.  I am just in the process of converting old backup tapes.  Our normal 
backup procedure is Monthly tapes, one for each month, for our offsite backup.  
Onsite we use smaller tapes and do a weekly backup.  Again these tapes are kept 
for 12 months and 52 weeks respectively.  However we also do a Fiscal Year 
Backup and a Calendar Year Backup.  These tapes are kept as long as possible.  
I started with DDS Tapes and progressed through DDS3 tapes, we then switched to 
VXA tapes.  I took all the DDS tapes I could read, wrote them back to disk then 
back to VXA Tapes.  We are in the process of switching to LTO for our platform, 
so I have just read in all the VXA tapes from Year End and FY End backups, 
wrote them back to disk.  I will shortly spin them off to LTO tapes.  However 
in about 6 months I will have to pull them back off this tape and write it 
again as we are again changing backup software.  I have gone through 4 
different backup programs over the life of this project and many tapes.  I do 
have backups of Year end and Fiscal Year end back to 1995.  There are a couple 
of incomplete backups in there as the old DDS tapes just couldn't be read.



And yes I have been asked to pull data off the old backups and look at it.  We 
had an error a few years ago that needed to be researched as to when it started 
and whose fault it was.  Being a Govt agency we had to research it and pull any 
information we could.  We were able to pull all needed data from our backups 
and prove error was not ours, even though we were blamed.  The other agency 
giving us the data could only go back 12-24 months to supply data.  But again I 
am lucky that we have a small data store so far.

Hello everyone.

For those who are still backing up to tape…

What do you guys have for tape backup policies?

I’m curious as to how far back you are keeping tapes – 1 year? 5 years?

I’ve typically seen a 10 tape rotation w/ a monthly tape put in offsite storage.

Is this still common practice?
